GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

.TH BMORE 1 "13 June 2000"
.SH NAME
bmore \- browse through a binary file
.SH SYNOPSIS
.B bmore
[
.B \-adi
] [
.B +\fIlinenumber\fP
] [
.B +/\fIASCII-pattern\fP
] [
.B +\\\\\fIHex-pattern\fP
] [
.I filename
\&.\|.\|. ]
.LP
.if n .ti +05i
.SH DESCRIPTION
.IX "bmore command" "" "\fLbmore\fP \(em browse binary file"
.IX "binary file, browse through" \fLbmore\fP
.IX file "browse bmore" "" "browse through binary\(em \fLbmore\fP"
.IX display "file by screenfuls \(em \fLbmore\fP"
.LP
.B more
is a filter that displays the contents of a binary
file
on the terminal, one screenful at a time. It normally pauses after
each screenful, and prints
.B --More--
at the bottom of the screen.
.B bmore
provides a two-line overlap between screens for continuity.
If
.B bmore
is reading from a file rather than a pipe, the percentage of
characters displayed so far is also shown.
.LP
.B bmore
scrolls up to display one more screen line in response to a
.SM RETURN
character; it displays another screenful in response to a
.SM SPACE
character. Other commands are listed below.
.LP
The screen is divided in three sections or panes:
The byte offset (extreme left), the hex pane (middle),
and an ascii pane (right) which shows as printable characters
those bytes in the hex pane.
On an 80 column terminal there will be sixteen hex values
and their ASCII values on each screen line.
Note that (as one would expect) the first byte has the offset \*(L'0\*(R' (zero).
.LP
.B bmore
sets the terminal
to
.I noecho
mode, so that the output can be continuous.
Commands that you type do not normally show up on your terminal,
except for the
.B /
,
.B \\\\
and
.B !
commands.
.LP
If the standard output is not a terminal,
.B more
acts just like
.BR cat (1V),
except that a header is printed before each file in a series.
.SH OPTIONS
.TP
.B \-a
ASCII mode: no hex representation of the contents. Non printable
characters are displayed as a dot (.)
.TP
.B \-d
Display error messages rather than ringing the terminal bell if
an unrecognized command is used.
This is helpful for inexperienced users.
.TP
.B \-i
Ignore case for searching.
.TP
.BI + linenumber\fP
Start up at
.IR linenumber .
.TP
.BI +/ ASCII-pattern\fP
Start up at the line containing the regular expression
.IR pattern .
Note: unlike
editors, this construct should
.I not
end with a
.RB ` / '.
If it does, then the trailing slash is taken as a character in the
search pattern.
.TP
.br
.ne 8
.SH USAGE
.SS Commands
.LP
The commands take effect immediately; it is not necessary to
type a carriage return.
Up to the time when the command character itself is given,
the user may type the line kill character to cancel the numerical
argument being formed.
In addition, the user may type the erase character to redisplay the
.RB ` "--More--(\fIxx\fP%)" '
message.
.LP
In the following commands,
.I i
is a numerical argument
.RB ( 1
by default).
.TP 10
.IR i \s-1SPACE\s0
Display another screenful, or
.I i
more lines if
.I i
is specified.
.TP
.IR i \s-1RETURN\s0
Display another line, or
.I i
more lines, if specified.
.TP
.IB i ^D
(\s-1CTRL\s0\-D)
Display (scroll down) 11 more lines.
.I i
is given, the scroll size is set to
.IR i\| .
.TP
.IR i d
Same as
.BR ^D .
.TP
.IB i z
Same as
.SM SPACE,
except that
.IR i\| ,
if present, becomes the new default number
of lines per screenful.
.TP
.IB i s
Skip
.I i\|
lines and then print a screenful.
.TP
.IB i f
Skip
.I i
screenfuls and then print a screenful.
.TP
.IB i ^B
(\s-1CTRL-B\s0)
Skip back
.I i
screenfuls and then print a screenful.
.TP
.I b
Same as
.B ^B
(\s-1CTRL-D\s0).
.TP
.B q
.PD 0
.TP
.B Q
.PD
Exit from
.BR more .
.TP
.B =
Display the current line number.
.TP
.B v
Drop into the
.BR bvi (1)
editor at the current offset of the current
file.
.TP
.B w
Drop into the
.BR bvi (1)
editor at the current offset of the current
file. Only the portion of the file displayed on the screen will be loaded.
.TP
.B h
Help. Give a description of all the
.B more
commands.
.TP
.IB i / pattern
Search for the
.IR i\| th
occurrence of the regular expression
.IR pattern .
Display the screenful starting at the file position
that contains the
.IR i\| th
match for the regular expression
.IR ASCII-pattern ,
or the end of a pipe, whichever comes first. If
.B bmore
is displaying a file and there is no such match, its position
in the file remains unchanged. Regular expressions can be
edited using erase and kill characters.
Erasing back past the first column cancels the search command.
.TP
.B \'
Single quote. Go to the point from which the last search started.
If no search has been performed in the current file,
go to the beginning of the file.
.TP
.BI ! command
Invoke a shell to execute
.IR command\| .
The characters
.B %
and
.BR ! ,
when used within
.I command
are replaced with the current filename
and the previous shell command,
respectively.
If there is no current filename,
.B %
is not expanded. Prepend a backslash to these characters to
escape expansion.
.TP
.IB i :n
Skip to the
.IR i\| th
next filename given in the command line,
or to the last filename in the list if
.I i
is out of range.
.TP
.IB i :p
Skip to the
.IR i\| th
previous filename given in the command line,
or to the first filename if
.I i
is out of range.
If given while
.B more
is positioned within a file, go to the
beginning of the file.
If
.B more
is reading from a pipe,
.B more
simply rings the terminal bell.
.br
.ne 2
.TP
.B :f
Display the current filename and offset number.
.br
.ne 5
.TP
.B :q
.PD 0
.TP
.B :Q
.PD
Exit from
.B bmore
(same as
.B q
or
.B Q ).
.TP
.B \&.
Dot. Repeat the previous command.

mmoorree is a filter that displays the contents of a binary
file on the terminal, one screenful at a time. It nor­
mally pauses after each screenful, and prints ----MMoorree---- at
the bottom of the screen. bbmmoorree provides a two-line over­
lap between screens for continuity. If bbmmoorree is reading
from a file rather than a pipe, the percentage of charac­
ters displayed so far is also shown.
bbmmoorree scrolls up to display one more screen line in
response to a RETURN character; it displays another
screenful in response to a SPACE character. Other com­
mands are listed below.
The screen is divided in three sections or panes: The byte
offset (extreme left), the hex pane (middle), and an ascii
pane (right) which shows as printable characters those
bytes in the hex pane. On an 80 column terminal there
will be sixteen hex values and their ASCII values on each
screen line. Note that (as one would expect) the first
byte has the offset 0 (zero).
bbmmoorree sets the terminal to _n_o_e_c_h_o mode, so that the output
can be continuous. Commands that you type do not normally
show up on your terminal, except for the // , \\ and !! com­
mands.
If the standard output is not a terminal, mmoorree acts just
like ccaatt(1V), except that a header is printed before each
file in a series.
OOPPTTIIOONNSS
--aa ASCII mode: no hex representation of the contents.
Non printable characters are displayed as a dot (.)
--dd Display error messages rather than ringing the ter­
minal bell if an unrecognized command is used.
This is helpful for inexperienced users.
--ii Ignore case for searching.
++_l_i_n_e_n_u_m_b_e_r
Start up at _l_i_n_e_n_u_m_b_e_r.
++//_A_S_C_I_I_-_p_a_t_t_e_r_n
Start up at the line containing the regular

expression _p_a_t_t_e_r_n. Note: unlike editors, this
construct should _n_o_t end with a `//'. If it does,
then the trailing slash is taken as a character in
the search pattern.

The commands take effect immediately; it is not necessary
to type a carriage return. Up to the time when the com­
mand character itself is given, the user may type the line
kill character to cancel the numerical argument being
formed. In addition, the user may type the erase charac­
ter to redisplay the `----MMoorree----((_x_x%%))' message.
In the following commands, _i is a numerical argument (11 by
default).
_iSPACE Display another screenful, or _i more lines if _i
is specified.
_iRETURN Display another line, or _i more lines, if speci­
fied.
_i^^DD (CTRL-D) Display (scroll down) 11 more lines. _i
is given, the scroll size is set to _i.
_id Same as ^^DD.
_izz Same as SPACE, except that _i, if present,
becomes the new default number of lines per
screenful.
_iss Skip _i lines and then print a screenful.
_iff Skip _i screenfuls and then print a screenful.
_i^^BB (CTRL-B) Skip back _i screenfuls and then print a
screenful.
_b Same as ^^BB (CTRL-D).
qq
QQ Exit from mmoorree.
== Display the current line number.
vv Drop into the bbvvii(1) editor at the current off­
set of the current file.
ww Drop into the bbvvii(1) editor at the current off­
set of the current file. Only the portion of the

hh Help. Give a description of all the mmoorree com­
mands.
_i//_p_a_t_t_e_r_n Search for the _ith occurrence of the regular
expression _p_a_t_t_e_r_n. Display the screenful
starting at the file position that contains the
_ith match for the regular expression _A_S_C_I_I_-_p_a_t_­
_t_e_r_n, or the end of a pipe, whichever comes
first. If bbmmoorree is displaying a file and there
is no such match, its position in the file
remains unchanged. Regular expressions can be
edited using erase and kill characters. Erasing
back past the first column cancels the search
command.
´´ Single quote. Go to the point from which the
last search started. If no search has been per­
formed in the current file, go to the beginning
of the file.
!!_c_o_m_m_a_n_d Invoke a shell to execute _c_o_m_m_a_n_d. The charac­
ters %% and !!, when used within _c_o_m_m_a_n_d are
replaced with the current filename and the pre­
vious shell command, respectively. If there is
no current filename, %% is not expanded. Prepend
a backslash to these characters to escape expan­
sion.
_i::nn Skip to the _ith next filename given in the com­
mand line, or to the last filename in the list
if _i is out of range.
_i::pp Skip to the _ith previous filename given in the
command line, or to the first filename if _i is
out of range. If given while mmoorree is positioned
within a file, go to the beginning of the file.
If mmoorree is reading from a pipe, mmoorree simply
rings the terminal bell.
::ff Display the current filename and offset number.
::qq
::QQ Exit from bbmmoorree (same as qq or QQ ))..
.. Dot. Repeat the previous command.

This command provides a means for collecting a series of \*(L"ex\*(R"
(colon) commands into a script file, then using this file to edit
other files. Since there is no binary stream editor \*(L"bsed\*(R", you
can use this option to make several global changes in a binary file.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Bvi stands for \*(L"Binary VIsual editor\*(R".
Bvi is a screen oriented editor for binary files;
its command set is based on that of the \fIvi\fR\|(1) text editor.
As a binary editor does not have the concept of \*(L"lines\*(R"
there are differences from Vi commands wherever the latter are
line orientate.
.SH "COMPARISON"
.IX Header "COMPARISON"
The main differences between Vi and Bvi are:
.PP
The screen is divided in three sections or panes:
The byte offset (extreme left), the hex pane (middle),
and an ascii pane (right) which shows as printable characters
those bytes in the hex pane.
On an 80 column terminal there will be sixteen hex values
and their ASCII values on each screen line.
Note that (as one would expect) the first byte has the offset \*(L'0\*(R' (zero).
.PP
You can toggle between the hex and ascii windows with the tab key (TAB).
Toggling between these two windows does not change the current
position (offset) within the file.
.PP
No \*(L"lines\*(R" concept:
Files are treated as one long stream of bytes. The characters
\*(L"newline\*(R" and \*(L"carriage return\*(R" are not special, id est they
never mark the end of lines. Therefore the lines on the screen do not
represent lines in the usual way. Data is broken across screen lines
arbitarily.
As a consequence there are no commands in bvi from ex or vi
that are based on line numbers, eg \*(L"dd\*(R", \*(L"yy\*(R", \*(L'C\*(R', \*(L'S\*(R', \*(L'o\*(R', \*(L'O\*(R'.
This also changes the meaning of \*(L"range\*(R" before the \*(L":write\*(R" command
to a byte offset, ie the command \*(L":100,200w foo\*(R" writes all *bytes*
(not lines) from offset 100 to offset 200 to the file \*(L"foo\*(R".
.PP
No \*(L"text objects":
There are also no text-specific arrangements like words,
paragraphs, sentences, sections and so on.
.PP
Extended \*(L"ruler":
The bottom line of the screen shows the current address (byte offset)
and the current character in these notations:
.PP
.Vb 1
\& octal, hexadecimal, decimal and ascii.
.Ve
Search patterns:
All search commands understand these special characters:
.PP
.Vb 3
\& . any character
\& [] set of characters
\& * zero or more occurrences of previous char or set
.Ve
But as there is no concept of lines you cannot use the standard symbols
("anchors") for \*(L"begin-of-line\*(R" ('^') and \*(L"end-of-line\*(R" ('$').
Searching for the start/end of lines must be done explicitly
by adding these special characters to your search pattern
using these meta sequences:
.PP
.Vb 4
\& \en newline
\& \er return
\& \et tab
\& \e0 binary zero
.Ve
Additional search commands:
Similar to the text search commands there are additional hex-search
functions \*(L'\e\*(R' and \*(L'#\*(R' which allow to search for any byte value.
Example: \*(L"\e62 76 69\*(R" will search for the string \*(L"bvi\*(R".
Spaces between hex value are optional, so searching
for \*(L"6775636B6573\*(R" will find \*(L"guckes\*(R".
.PP
Changing the length of data (insertion, deletion) moves the data to other addresses;
this is bad for many cases (eg. databases, program files) and is
thus disabled by default. You can enable this commands by typing
.PP
\f(CW :set memmove\fR
.PP
\fBBVI Modes:\fR
.PP
Command Mode (Normal Mode):
.PP
Input is treated as command. Note that command mode is the default
mode after startup and after escaping from input mode.
Use ESC (escape) to cancel a partial (uncompleted) command.
.PP
Input Mode:
.PP
Input is treated as replacement of current characters or
(after the end of the file) is appended
to the current file. This mode is entered from command mode by
typing one of \*(L'i\*(R', \*(L'I\*(R', \*(L'A\*(R', \*(L'r\*(R', or \*(L'R\*(R'.
You can enter the characters from the keyboard (in the ASCII window) or
hexadecimal values (in the HEX window).
Type TAB to switch between these two windows.
Type ESC to finish the current input and return to command mode.
Type CTRL\-C to cancel current command abnormally.
.PP
Command line mode (Last Line Mode or : mode):
.PP
Similar to vi, this mode is entered by typing one of the
characters
: / ? \e # !
The command is terminated and executed by typing a carriage
return; to cancel a partially typed command, type
ESC to cancel the current command and return to command mode.
.SH "ENVIRONMENT"
.IX Header "ENVIRONMENT"
The editor recognizes the environment variable BVIINIT as a
command (or list of commands) to run when it starts up. If
this variable is undefined, the editor checks for startup
commands in the file \fI~/.bvirc\fR file, which you must own.
However, if there is a \fI.bvirc\fR owned by you in the current
directory, the editor takes its startup commands from this
file \- overriding both the file in your home directory and
the environment variable.
.SH "TERMINOLOGY"
.IX Header "TERMINOLOGY"
Characters names are abbreviated as follows:
Abbr. ASCII name aka
CR 010 carriage return
^A 001 control-a
^H 008 control-h
^I 009 control-i aka TAB
^U 021 control-u

.PP
\fBAdditional edit commands\fR
You can insert/append/change bytes in ASCII/binary/decimal/
hexadecimal or octal representation. You can enter several
(screen) lines of input. A line with only a period (.) in it
will terminate the command. You must not type in values greater
than a byte value. This causes an abandonment of the command.
Pressing the CR key does not insert a newline \- character into
the file. If you use ASCII mode you can use the special characters
\en, \er, \et and \e0.

\*(L'\*(R' move cursor to previous context in ASCII section
`` move cursor to previous context in HEX section
\fBLine positioning:\fR
H jump to first line on screen ("top")
L jump to last line on screen ("low")
M jump to middle line on screen ("middle")
\- jump onto previous line on screen
+ jump onto next line on screen
CR same as +
DOWN or j next line, same column
UP or k previous line, same column
.PP
\fBCharacter positioning:\fR
^ first byte in HEX window
$ end of screen line
l or RIGHT jump onto next byte (within current
screen line)

ESC ends insertion, back to command mode
.PP
\fBAppend and replace:\fR
A append at end of file
rx replace current bte with char \*(L'x\*(R'
R enter replace mode; for all subsequent input,
the current byte is overwritten with the next
input character; leave replace mode with ESC.
.PP
\fBMiscellaneous Operations:\fR
TAB toggle between ASCII and HEX section
.PP
\fBYank and Put:\fR
3ySPACE yank 3 characters
p insert contents of yank buffer
o replace text with content of yank buffer
P put back at end of file
.PP
\fBUndo, Redo:\fR
u undo last change
Note: Only the last change can be undone.
Therefore this commands toggles between the
last and second-t-last state of the buffer.

BVI(1) User Commands BVI(1)
NAME
bvi, bview - visual display editor for binary files
VERSION
bvi-1.2.0
SYNOPSIS
bvi [-R] [-c cmd] [-f script] file...
bview [-R] [-c cmd] [-f script] file...
OPTIONS
file...
One or more files. The file argument indicates one or
more files to be edited.
-R "Readonly": The readonly flag is set for all the
files, preventing accidental overwriting with a write
command.
-c cmd
Execute command cmd. Begin editing by executing the
specified editor command (usually a search or
positioning command).
-f script
This command provides a means for collecting a series
of "ex" (colon) commands into a script file, then
using this file to edit other files. Since there is no
binary stream editor "bsed", you can use this option
to make several global changes in a binary file.
DESCRIPTION
Bvi stands for "Binary VIsual editor". Bvi is a display
oriented editor for binary files; its command set is based
on those of the vi(1) texteditor. As a binary editor
cannot have the concept of "lines" there are several
differences to Vi commands (see COMPARISON).
COMPARISON
The main differences between Vi and Bvi are:
The screen is divided in three sections/windows: The byte
offset (at the left side), the hex window (in the middle),
and the ascii window (to the right) which shows the ascii
values of those bytes in the hex window. On an 80 column
terminal you will therefore see sixteen hex values and
their ASCII values on each screen line. Note that the
first byte has the offset '0' (zero).
You can toggle between the hex and ascii windows with the
tabulator key (TAB). Toggling between these two windows
does not change the current position within the file.
No "lines" concept: Files are treated as one long series
of bytes only. These characters "newline" and "carriage
return" thus are not special, ie they do not mark the end
of lines. Therefore the lines on the screen do not
represent lines in the usual way. Data is broken across
screen lines as they happen to fit in. As a consequence
there are no commands in bvi from ex or vi that are based
on line numbers, eg "dd", "yy", 'C', 'S', 'o', 'O'. This
also changes the meaning of "range" before the ":write"
command to a byte offset, ie the command ":100,200w foo"
writes all *bytes* (not lines) from offset 100 to offset
200 to the file "foo".
No "text objects": There are also no text-specific
arrangements like words, paragraphs, sentences, sections
and so on.
Extended "ruler": The bottom line of the screen shows the
current address (byte offset) and the current character in
these notations:
octal, hexadecimal, decimal and ascii.
Search patterns: All search commands understand these
special characters:
. any character
[] set of characters
* zero or more occurrences of previous char or set
But as there is no concept of lines you cannot use the
standard symbols ("anchors") for "begin-of-line" ('^') and
"end-of-line" ('$'). Searching for the start/end of lines
must be done explicitly by adding these special characters
to your search pattern using these meta sequences:
\n newline
\r return
\t tab
\0 binary zero
Additional search commands: Similar to the text search
commands there are additional hex-search functions '\' and
'#' which allow to search for any byte value. Example:
"\62 76 69" will search for the string "bvi". Spaces
between hex value are optional, so searching for
"6775636B6573" will find "guckes".
Changing data (insertion, deletion) moves the data to
other addresses; this is bad for many cases (eg.
databases, program files) and is thus disabled by default.
You can enable this commands by typing
:set memmove
BVI Modes:
Command Mode aka Normal Mode:
Input is treated as commands. Note that command mode is
the default mode after startup and when you escape/quit
from either command line mode or input mode. Use ESC
(escape) to cancel a partial (uncompleted) command.
Input Mode:
Input is treated as replacement of current character or is
appended to the current file. This mode is entered from
command mode by typing either of 'i', 'I', 'A', 'r', or
'R'. You can enter the character itself (in the ASCII
window) or its hexadecimal value (in the HEX window).
Type TAB to switch between these two windows. Type ESC to
cancel current command and return to command mode. Type
CTRL-C to cancel current command abnormally.
Command line mode (aka Last Line Mode):
Reading input for : / ? \ # or !; terminate by typing a
carriage return; an interrupt cancels termination. Type
ESC to cancel current command and return to command mode.
ENVIRONMENT
The editor recognizes the environment variable BVIINIT as
a command (or list of commands) to run when it starts
up. If this variable is undefined, the editor checks for
startup commands in the file ~/.bvirc file, which you
must own. However, if there is a .bvirc owned by you in
the current directory, the editor takes its startup
commands from this file - overriding both the file in your
home directory and the environment variable.
TERMINOLOGY
Characters names are abbreviated as follows:
Abbr. ASCII name aka
CR 010 carriage return
^A 001 control-a
^H 008 control-h
^I 009 control-i aka TAB
^U 021 control-u
^Z 026 control-z
ESC 027 escape aka ESC
DEL 127 delete
LEFT --- left arrow
RIGHT --- right arrow
DOWN --- down arrow
UP --- up arrow
COMMAND SUMMARY
See the TERMINOLOGY for a summary on key name
abbreviations used within the following description of
commands.
Abstract:
Arrow keys move the cursor on the screen within the
current window.
Sample commands:
:version show version info
<- v ^ -> arrow keys move the cursor
h j k l same as arrow keys
u undo previous change
ZZ exit bvi, saving changes
:q! quit, discarding changes
/text search for text
^U ^D scroll up or down
Counts before bvi commands:
Numbers may be typed as a prefix to some commands.
They are interpreted in one of these ways.
screen column |
byte of file G
scroll amount ^D ^U
repeat effect most of the rest
Interrupting, canceling
ESC end insert or incomplete command
DEL (delete or rubout) interrupts
File manipulation:
ZZ if file modified, write and exit;
otherwise, exit
:w write changed buffer to file
:w! write changed buffer to file, overriding
read-only ("forced" write)
:q quit when no changes have been made
:q! quit and discard all changes
:e file edit file
:e! reedit current file, discard all changes
:e # edit the alternate file
:e! # edit the alternate file, discard changes
:w file write current buffer to file
:w! file write current buffer to file overriding
read-only (this "overwrites" the file)
:sh run the command as set with option "shell",
then return
:!cmd run the command cmd from "shell", then
return
:n edit next file in the argument list
:f show current filename, modified flag,
current byte offset, and percentage of
current position within buffer
^G same as :f
Additional edit commands
You can insert/append/change bytes in
ASCII/binary/decimal/ hexadecimal or octal representation.
You can enter several (screen) lines of input. A line with
only a period (.) in it will terminate the command. You
must not type in values greater than a byte value. This
causes an abandom of the command. Pressing the CR key
does not insert a newline - character into the file. If
you use ASCII mode you can use the special characters \n,
\r, \t and \0.
:i aCR insert bytes (ASCII) at cursor position
:a bCR append bytes (Binary) at end of file
:c hCR change bytes (hexadecimal) at cursor position
Bit-level operations
:and n bitwise 'and' operation with value n
:or n bitwise 'or' operation with value n
:xor n bitwise 'xor' operation with value n
:neg two's complement
:not logical negation
:sl i shift each byte i bits to the left
:sr i shift each byte i bits to the right
:rl i rotate each byte i bits to the left
:rr i rotate each byte i bits to the right
Command mode addresses
:w foo write current buffer to a file
named "foo"
:5,10w foo copy byte 5 through 100 into as
file named foo
:.,.+20w foo copy the current byte and the next
20 bytes to foo
:^,'aw foo write all bytes from the beginning
through marker 'a'
:/pat/,$ foo search pattern pat and and copy
through end of file
Positioning within file:
^B backward screen
^F forward screen
^D scroll down half screen
^U scroll up half screen
nG go to the specified character
(end default), where n is a decimal address
/pat next line matching pat
?pat previous line matching pat
\hex jump to next occurrence of hex string hex
#hex jump to previous occurrence of hex string hex
n repeat last search command
N repeat last search command, but in opposite
direction
Adjusting the screen:
^L clear and redraw screen
zCR redraw screen with current line at top of screen
z- redraw screen with current line at bottom of
screen
z. redraw screen with current line at center of
screen
/pat/z- search for pattern pat and then move currents
line to bottom
^E scroll screen down 1 line
^Y scroll screen up 1 line
Marking and returning:
mx mark current position with lower-case letter x
Note: this command works for all lower-case
letters
'x move cursor to mark x in ASCII section
`x move cursor to mark x in HEX section
'' move cursor to previous context in ASCII section
`` move cursor to previous context in HEX section
Line positioning:
H jump to first line on screen ("top")
L jump to last line on screen ("low")
M jump to middle line on screen ("middle")
- jump onto previous line on screen
+ jump onto next line on screen
CR same as +
DOWN or j next line, same column
UP or k previous line, same column
Character positioning:
^ first byte in HEX window
$ end of screen line
l or RIGHT jump onto next byte (within current
screen line)
h or LEFT jump onto previous byte (within current
screen line)
^H same as LEFT
space same as RIGHT
fx find next occurrence of character x
Fx find previous occurrence of character x
n| jump onto nth byte/character within current
line
Strings:
(works similar to the strings(1) command)
Note: "Words" are defined as strings of "nonprinting
characters".
e jump to next end of word
w jump to next begin of word
b jump to previous begin of word
W forward to next string delimited with a
\0 or \n
B back to previous string delimited with a
nonprinting char
Corrections during insert:
^H erase last character (backspace)
erase your erase character, same as ^H (backspace)
ESC ends insertion, back to command mode
Append and replace:
A append at end of file
rx replace current bte with char 'x'
R enter replace mode; for all subsequent input,
the current byte is overwritten with the next
input character; leave replace mode with ESC.
Miscellaneous Operations:
TAB toggle between ASCII and HEX section
Yank and Put:
3ySPACE yank 3 characters
p insert contents of yank buffer
o replace text with content of yank buffer
P put back at end of file
Undo, Redo:
u undo last change
Note: Only the last change can be undone.
Therefore this commands toggles between the
last and second-t-last state of the buffer.
Setting Options:
With the :set command you can set options in bvi
Option Default Description
autowrite noaw Save current file, if modified, if you
give a :n, :r or ! command
columns cm=16 on an 80 character wide terminal
ignorecase noic Ignores letter case in searching
magic nomagic Makes . [ * special in patterns
memmove nomm enables insert and delete commands
offset of=0 adds an offset to the diplayed addresses
readonly noro If set, write fails unless you use ! after command
scroll sc=1/2 window
Number of lines scrolled by ^U and ^D
showmode mo Displays statusline on bottom of the screen
terse noterse Let you obtain shorter error messages
window window=screensize
Lines in window, can be reduced at slow terminals
wordlength wl=4 Length of an ASCII-string found by w, W, b or B
wrapscan ws Searches wrap around past the end of the file
unixstyle nous The representation of ascii characters below
32 is displayed in the statusline as shown
in ascii(7) if unset rather in DOS-style (^A)

<p>
<STRONG>bmore</STRONG> is a filter that displays the contents of a binary
file on the terminal, one screenful at a time. It normally pauses after each
screenful, and prints <B>--More--</B> at the bottom of the screen.
<STRONG>bmore</STRONG> provides a two-line over­ lap between screens for
continuity. If bmore is reading from a file rather than a pipe,
the percentage of characters displayed so far is also shown.
<P>
<STRONG>bmore</STRONG> scrolls up to display one more screen line in
response to a RETURN character; it displays another
screenful in response to a SPACE character. Other commands are listed below.
<P>
The screen is divided in three sections or panes: The byte
offset (extreme left), the hex pane (middle), and an ascii
pane (right) which shows as printable characters those
bytes in the hex pane. On an 80 column terminal there
will be sixteen hex values and their ASCII values on each
screen line. Note that (as one would expect) the first
byte has the offset 0 (zero).

<BLOCKQUOTE>
When forming a colon command, the first character, the colon, can be
followed by zero, one or two addresses. These addresses are byte
addresses, in contrast to vi, which uses line addresses.<BR>
The byte addresses can be given in decimal notation or, with a
leading zero, in hexadecimal notation. If you have specified an
address offset (e.g. <B>:set offset=256</B>), this offset has to be
added to the byte addresses.<BR>
Without an address, the whole file is affected or the current cursor
position is used (depending of the command).

<P>
If you would like to use the insert and delete commands, you have to
enable them with the <B>:set memmove</B> option. These commands are
locked per default, because you must not move bytes to a different
address for many types of binary files (e.g. executables, database files,
etc.). If you usually edit files where bytes can be moved, you can add
the <B>:set memmove</B> directive to your <B><TT>.bvirc</TT></B> file.

<p>
Der BVI (Binary-VI) ist ein Editor für Binärfiles. Seine Kommandos sind
weitgehend an den Standard UNIX Editor VI(1) angelehnt. Der Bildschirm
ist in einen hexadezimalen und einen ASCII-Bereich geteilt. Einige zusätzliche
Kommandos wurden zugefügt, einige Kommandos adaptiert und einige Kommandos,
die bei Binärfiles keinen Sinn machen, wurden weggelassen. Für eine
Gesamtübersicht siehe Manual Page BVI(1).
<H2>Zusätzliche Kommandos</H2>
Eine wichtige Funktion für binäre Files ist das Suchen nach Hexcodes.
Dafür gibt es analog zum '/' und '?' - Kommando zusätzlich das '\' und
das '#' - Kommando.<BR>
Beispiel:<BR>
\1e f4 56 - Sucht die angegebene Bytefolge in vorwärts-Richtung<BR>
#34 5a a4 - Sucht Bytefolge rückwärts.
<P>
Die normalen Textsuchkommandos sind auch vorhanden, wobei zusätzlich ein
Return, Linefeed oder NULL im Suchstring aufscheinen darf (\n \r oder \0).
<P>
Die Kommandos w, W, b, B (nächstes oder vorhergehendes Wort) wurden insoweit
abgeändert, daß sie eher dem STRINGS(1) - Kommando entsprechen, also in
einem Binärfile Textstrings suchen. Dabei sucht W und B nach Strings, die
mit einem \0 oder \n enden, w und b sucht nach Strings, die mit einem
beliebigen, nicht druckbaren Zeichen enden. Die Stringlänge beträgt 4 Zeichen,
wobei mit ":set wordlength=x" die Stringlänge auf x Zeichen eingestellt werden
kann.
<P>
Der Bildschirm ist in einen HEX und einen ASCII-Bereich aufgeteilt, wobei
jederzeit mit der TAB - Taste von einem Bereich in den anderen gewechselt
werden kann (auch im Eingabemodus). Es kann also bei der Eingabe zwischen
normalen ASCII-Zeichen und Hex-Eingabe hin- und hergesprungen werden.
<P>
Am unteren Bildrand befindet sich eine Statusanzeige, welche die Adresse des
Bytes, auf welchem der Cursor momentan steht, anzeigt. Außerdem wird das Byte
in oktaler, hexadezimaler, dezimaler und ASCII-Repräsentation anzeigt. Die
ASCII-Anzeige kann von DOS-Style (27 entspricht ^Z) auf UNIX-Style entsprechend
Manual Page ASCII(7) umgeschaltet werden (27 entspricht SUB).
Kommando ist ":set unixstyle". Die Statusanzeige kann mit ":set noshowmode"
ausgeschaltet werden.
<H2>Regular Expressions</H2>
Für die Suchkommandos sowohl für Text als auch Hex sind Regular Expressions
zulässig, wobei es die Zeichen ^ und $ für Zeilenanfang und Zeilenende nicht
gibt. Die Kombination .* ist unzulässig, da sie sich auf jeden Fall auf das
Ende des Files beziehen würde.
<H2>Zeilen</H2>
Da es in binären Files keine Zeilen gibt (die Darstellung der einzelnen
Zeilen am Bildschirm hat keinen Bezug zum File) gibt es keinerlei
zeilenorientierte Kommandos (dd, o, O, yy). Ein Kommando
wie :s/XXX/UUU/g ändert somit das gesamte File. Zu beachten ist auch, daß
:s/XX/UUUU/ nicht die beiden X durch vier U ersetzt, sondern die beiden den
X folgenden Zeichen auch durch U überschrieben werden.
<H2>Editierkommandos</H2>
Da binäre Files häufig ausführbare Programme oder Datenbankfiles sind,
bei denen Bytes nicht einfach an eine andere Adresse verschoben werden
d&uuml;rfen, sind Einf&uuml;ge- und L&ouml;schkommandos (z.B. a, i, x)
deaktiviert. Mit dem Kommando <B>:set memmove</B> k&ouml;nnen sie
aktiviert werden.
<P>
Die Kommandos <B>:a</B> (append), <B>:c</B> (change) und <B>:i</B> (insert)
k&ouml;nnen benutzt werden, um ein oder mehrere Bytes in ASCII, bin&auml;rer,
dezimaler, hexadezimaler oder oktaler Schreibweise einzugeben
(a, b, d, h oder o). Es
k&ouml;nnen mehrere (Bildschirm) Zeilen eingegeben werden. Das Kommando
wird beendet, sobald eine Zeile, die nur aus einem Punkt besteht,
eingegeben wird.
<P>
Beispiel:
<BLOCKQUOTE>
<PRE>
:i b
1 1001 010101 1111
11111 1010 1 0 1
.
</PRE>
</BLOCKQUOTE>
Zu beachten ist, da&szlig; kein Einzelwert den maximalen Byte-Wert (255)
&uuml;berschreiten darf, da sonst die Eingabe abgebrochen wird. Das
Dr&uuml;cken der RETURN - Taste f&uuml;hrt zu keinem "RETURN" - Zeichen in
der Datei, im ASCII - Modus k&ouml;nnen allerdings die Sonderzeichen
\n, \r, \t und \0 benutzt werden.
<H2>Yank und Put</H2>
Auch hier gilt eine etwas geänderte Funktion. Das <B>y</B> (yank) -
Kommando ist allerdings ab Version 1.2.0 dem Vi angenähert:<BR>
<TABLE>
<TR><TD>5ySPACE</TD><TD>kopiert 5 Zeichen in den Yank-Buffer</TD></TR>
<TR><TD>o</TD><TD>überschreibt an Cursor - Position die folgenden Zeichen
mit dem Inhalt des Yank- oder Delete - Puffers</TD></TR>
<TR><TD>p</TD><TD>fügt an der Cursor - Position den Inhalt des Yank-
oder Delete - Puffers ein.</TD></TR>
<TR><TD>P</TD><TD>fügt den Inhalt des Yank- oder Delete - Puffers am Dateiendes
an.</TD></TR>
</TABLE>
<P>
Das Kommando ":r filename" fügt das angegebene File nicht an der Cursor-
Position sondern am Dateiende an.
<H2>Adressen</H2>
Das Kommando nG führt nicht zur n. Zeile, sondern zum n. Byte.
Die Eingabe der Nummer wird dezimal interpretiert. Um eine Adresse
hexdezimal angeben zu können, kann g eingegeben werden. Es erscheint ein
Prompt in der Statuszeile, bei dem eine hexadezimale Eingabe erfolgen kann.
Das erste Byte hat Adresse 0.<BR>
Die Anzeige der Adressen kann mit einem Offset versehen werden
(:set offset=256), beispielsweise um für .COM Files in DOS einen Beginn
bei Adresse 100Hex anzuzeigen. Wird ein offset=1 angegeben, so ist
hat das erste Byte Adresse 1. Das G - Kommando berücksichtigt den Offset.
Im Gegensatz dazu zeigt das :f - Kommando immer die Ordnungszahl des
Bytes an, beginnend mit 1 ohne Berücksichtigung des Offsets.
<H2>Bitweise Kommandos</H2>
Um Manipulationen auf Bit-Ebene durchf&uuml;hren zu k&ouml;nnen, stehen
folgende Kommandos zur Verf&uuml;gung:
<CENTER><TABLE>
<TR><TD><B>:rl </B><I>n</I></TD><TD>Rotiert Bits links</TD><TD ROWSPAN=4>
<I>n</I> ist eine Zahl zwischen 1 und 7</TD></TR>
<TR><TD><B>:rr </B><I>n</I></TD><TD>Rotiert Bits rechts</TD></TR>
<TR><TD><B>:sl </B><I>n</I></TD><TD>Schiebt Bits links</TD></TR>
<TR><TD><B>:sr </B><I>n</I></TD><TD>Schiebt Bits rechts</TD></TR>
<TR><TD><B>:and </B><I>i</I></TD><TD>Und Verkn&uuml;pfung</TD><TD ROWSPAN=4>
<I>i</I> ist eine Zahl zwischen 0 und 255</TD></TR>
<TR><TD><B>:or </B><I>i</I></TD><TD>Oder Verkn&uuml;pfung</TD></TR>
<TR><TD><B>:xor </B><I>i</I></TD><TD>Exklusiv-oder Verkn&uuml;pfung</TD></TR>
<TR><TD><B>:not </B></TD><TD>Negiert Bytewert</TD></TR>
<TR><TD><B>:neg </B></TD><TD>Zweier-Komplement</TD></TR>
</TABLE></CENTER>
Wird kein Bereich angegeben, so bezieht sich die Operation auf die gesamte
Datei. Es k&ouml;nnen zwei Adressen in den &uuml;blichen Schreibweisen
angegeben werden. Normalerweise wird dezimale Eingabe erwartet, bei
f&uuml;hrender 0 werden die Adressen Hexadezimal interpretiert.
<BR>Der Wert <B>i</B> f&uuml;r die logische Verkn&uuml;pfung kann
dezimal, hexadezimal, oder mit f&uuml;hrendem <I>B</I> in bin&auml;rer
Schreibweise angegeben werden. Auch bei Eingabe von genau acht 0 und 1
Werten wird der Byte - Wert bin&auml;r interpretiert.<BR>
Beispiel:<BR>
<BLOCKQUOTE CLASS="examp">
<B><TT>:100,500and 01A </TT><FONT COLOR=#AAAAAA>RETURN</FONT></B><BR>
<B><TT>:03FA,01000or 00001000 </TT><FONT COLOR=#AAAAAA>RETURN</FONT></B><BR>

The following steps are necessary to get bvi running:
<H2>UNIX</H2>
The Unix version of bvi needs the curses (ncurses) library
for cursor movement.
<OL>
<LI>Download the source package from the Download Page
<LI>Unzip the package with the command:
<PRE CLASS="examp">
# gunzip -c bvi-1.3.0.src.tar.gz | tar xvf
</PRE>
<LI>Change to the directory <TT CLASS="examp">bvi-1.3.0</TT> and type
<PRE CLASS="examp">
# ./configure
# make
</PRE>
<li>Type `<tt class="examp">make install</tt>' for copying the executable files
and manual pages to the final directories.
<br>
By default, `<tt class="examp">make install</tt>' will install the package's files in
<tt class="examp">`/usr/local/bin', `/usr/local/man'</tt>, etc.
You can specify an
installation prefix other than `<tt class="examp">/usr/local</tt>' by giving
`<tt class="examp">configure</tt>' the option
`<tt class="examp">--prefix=PATH</tt>'. Use the
`<tt class="examp">--with-ncurses</tt>' option to configure to specify an
alternate search path for Ncurses outside the normal
<tt class="examp">include/lib</tt> search path.
<p>
You will find now four new commands:
<pre class="examp">
bvi The binary editor
bview The readonly version of bvi
bedit The beginners version of bvi
bmore The binary more program
</pre>
<li>Use `<tt class="examp">make uninstall</tt>' to remove the installed
files from your file system.<br>
You can remove the program binaries and object files from the
source code directory by typing `<tt class="examp">make clean</tt>'.
To also remove the files that `<TT CLASS="examp">configure</tt>' created
(so you can compile the package for
a different kind of computer), type `<tt class="examp">make distclean</tt>'.
</ol>
<H2>MSDOS</H2>
You have to convert the sourcefiles from the UNIX textformat to
the MSDOS textformat first. This can be done e.g. by loading and
saving them with the MSDOS standard editor `edit'.
<P>
The MSDOS version is using the conio routines of the
Borland - C compilers for cursor movement. The <TT>doscur.h</TT>
header file substitutes the curses commands.<BR>
<strong>Bvi</strong> is using the "HUGE" memory model, <strong>bmore</strong>
needs the "TINY" model to
be able to convert it to a .COM file.
<OL>
<LI>Download the source package from the Download Page
<LI>Unzip the package with the command:
<PRE CLASS="examp">
gunzip -c bvi-1.3.0.src.tar.gz | tar xvf
</PRE>
<LI> Load the tcconfig file (located in the <TT>bc</TT> subdirectory
for Borland - C).
<LI> Press F9-Make

BMORE(1) BMORE(1)
NAME
bmore - browse through a binary file
SYNOPSIS
bmore [ -adi ] [ +linenumber ] [ +/ASCII-pattern ] [
+\Hex-pattern ] [ filename ... ]
DESCRIPTION
more is a filter that displays the contents of a binary
file on the terminal, one screenful at a time. It nor-
mally pauses after each screenful, and prints --More-- at
the bottom of the screen. bmore provides a two-line over-
lap between screens for continuity. If bmore is reading
from a file rather than a pipe, the percentage of charac-
ters displayed so far is also shown.
bmore scrolls up to display one more screen line in
response to a RETURN character; it displays another
screenful in response to a SPACE character. Other com-
mands are listed below.
The screen is divided in three sections or panes: The byte
offset (extreme left), the hex pane (middle), and an ascii
pane (right) which shows as printable characters those
bytes in the hex pane. On an 80 column terminal there
will be sixteen hex values and their ASCII values on each
screen line. Note that (as one would expect) the first
byte has the offset 0 (zero).
bmore sets the terminal to noecho mode, so that the output
can be continuous. Commands that you type do not normally
show up on your terminal, except for the / , \ and ! com-
mands.
If the standard output is not a terminal, more acts just
like cat(1V), except that a header is printed before each
file in a series.
OPTIONS
-a ASCII mode: no hex representation of the contents.
Non printable characters are displayed as a dot (.)
-d Display error messages rather than ringing the ter-
minal bell if an unrecognized command is used.
This is helpful for inexperienced users.
-i Ignore case for searching.
+linenumber
Start up at linenumber.
+/ASCII-pattern
Start up at the line containing the regular
expression pattern. Note: unlike editors, this
construct should not end with a `/'. If it does,
then the trailing slash is taken as a character in
the search pattern.
USAGE
Commands
The commands take effect immediately; it is not necessary
to type a carriage return. Up to the time when the com-
mand character itself is given, the user may type the line
kill character to cancel the numerical argument being
formed. In addition, the user may type the erase charac-
ter to redisplay the `--More--(xx%)' message.
In the following commands, i is a numerical argument (1 by
default).
iSPACE Display another screenful, or i more lines if i
is specified.
iRETURN Display another line, or i more lines, if speci-
fied.
i^D (CTRL-D) Display (scroll down) 11 more lines. i
is given, the scroll size is set to i.
id Same as ^D.
iz Same as SPACE, except that i, if present,
becomes the new default number of lines per
screenful.
is Skip i lines and then print a screenful.
if Skip i screenfuls and then print a screenful.
i^B (CTRL-B) Skip back i screenfuls and then print a
screenful.
b Same as ^B (CTRL-D).
q
Q Exit from more.
= Display the current line number.
v Drop into the bvi(1) editor at the current off-
set of the current file.
w Drop into the bvi(1) editor at the current off-
set of the current file. Only the portion of the
file displayed on the screen will be loaded.
h Help. Give a description of all the more com-
mands.
i/pattern Search for the ith occurrence of the regular
expression pattern. Display the screenful
starting at the file position that contains the
ith match for the regular expression ASCII-pat-
tern, or the end of a pipe, whichever comes
first. If bmore is displaying a file and there
is no such match, its position in the file
remains unchanged. Regular expressions can be
edited using erase and kill characters. Erasing
back past the first column cancels the search
command.
' Single quote. Go to the point from which the
last search started. If no search has been per-
formed in the current file, go to the beginning
of the file.
!command Invoke a shell to execute command. The charac-
ters % and !, when used within command are
replaced with the current filename and the pre-
vious shell command, respectively. If there is
no current filename, % is not expanded. Prepend
a backslash to these characters to escape expan-
sion.
i:n Skip to the ith next filename given in the com-
mand line, or to the last filename in the list
if i is out of range.
i:p Skip to the ith previous filename given in the
command line, or to the first filename if i is
out of range. If given while more is positioned
within a file, go to the beginning of the file.
If more is reading from a pipe, more simply
rings the terminal bell.
:f Display the current filename and offset number.
:q
:Q Exit from bmore (same as q or Q ).
. Dot. Repeat the previous command.

BVI(1) User Commands BVI(1)
NAME
bvi, bview - visual display editor for binary files
VERSION
bvi-1.3.0
SYNOPSIS
bvi [-R] [-c cmd] [-b begin] [-e end] [-s size] [-f script] file...
bview [-R] [-c cmd] [-b begin] [-e end] [-s size] [-f script] file...
OPTIONS
file...
A list of filenames. The first one will be the
current file and will be read into the buffer. The
cursor will be positioned on the first line of the
buffer. You can get to the other files with the
":next" command.
-R "Readonly": The readonly flag is set for all the
files, preventing accidental overwriting with a write
command.
-b begin
causes bvi to load a file not from the start but from
offset {begin}.
-e end
causes bvi to load a file not till end but till address
{end}.
-s size
causes bvi not to load the complete file but only
{size} bytes.
-c cmd
{cmd} will be executed after the first file has
been read. If the {cmd} contains spaces it must
be enclosed in double quotes (this depends on the
shell that is used).
-f script
This command provides a means for collecting a series
of "ex" (colon) commands into a script file, then
using this file to edit other files. Since there is no
binary stream editor "bsed", you can use this option
to make several global changes in a binary file.
DESCRIPTION
Bvi stands for "Binary VIsual editor". Bvi is a screen
oriented editor for binary files; its command set is based
on that of the vi(1) text editor. As a binary editor does
not have the concept of "lines" there are differences from
Vi commands wherever the latter are line orientate.
COMPARISON
The main differences between Vi and Bvi are:
The screen is divided in three sections or panes: The byte
offset (extreme left), the hex pane (middle), and an ascii
pane (right) which shows as printable characters those
bytes in the hex pane. On an 80 column terminal there
will be sixteen hex values and their ASCII values on each
screen line. Note that (as one would expect) the first
byte has the offset '0' (zero).
You can toggle between the hex and ascii windows with the
tabulator key (TAB). Toggling between these two windows
does not change the current position within the file.
No "lines" concept: Files are treated as one long stream
of bytes. The characters "newline" and "carriage return"
are not special, id est they never mark the end of lines.
Therefore the lines on the screen do not represent lines
in the usual way. Data is broken across screen lines
arbitarily. As a consequence there are no commands in bvi
from ex or vi that are based on line numbers, eg "dd",
"yy", 'C', 'S', 'o', 'O'. This also changes the meaning
of "range" before the ":write" command to a byte offset,
ie the command ":100,200w foo" writes all *bytes* (not
lines) from offset 100 to offset 200 to the file "foo".
No "text objects": There are also no text-specific
arrangements like words, paragraphs, sentences, sections
and so on.
Extended "ruler": The bottom line of the screen shows the
current address (byte offset) and the current character in
these notations:
octal, hexadecimal, decimal and ascii.
Search patterns: All search commands understand these
special characters:
. any character
[] set of characters
* zero or more occurrences of previous char or set
But as there is no concept of lines you cannot use the
standard symbols ("anchors") for "begin-of-line" ('^') and
"end-of-line" ('$'). Searching for the start/end of lines
must be done explicitly by adding these special characters
to your search pattern using these meta sequences:
\n newline
\r return
\t tab
\0 binary zero
Additional search commands: Similar to the text search
commands there are additional hex-search functions '\' and
'#' which allow to search for any byte value. Example:
"\62 76 69" will search for the string "bvi". Spaces
between hex value are optional, so searching for
"6775636B6573" will find "guckes".
Changing data (insertion, deletion) moves the data to
other addresses; this is bad for many cases (eg.
databases, program files) and is thus disabled by default.
You can enable this commands by typing
:set memmove
BVI Modes:
Command Mode (Normal Mode):
Input is treated as command. Note that command mode is
the default mode after startup and after escaping from
input mode. Use ESC (escape) to cancel a partial
(uncompleted) command.
Input Mode:
Input is treated as replacement of current characters or
(after the end of the file) is appended to the current
file. This mode is entered from command mode by typing
one of 'i', 'I', 'A', 'r', or 'R'. You can enter the
characters from the keyboard (in the ASCII window) or
hexadecimal values (in the HEX window). Type TAB to
switch between these two windows. Type ESC to finish the
current input and return to command mode. Type CTRL-C to
cancel current command abnormally.
Command line mode (Last Line Mode or : mode):
Similar to vi, this mode is entered by typing one of the
characters : / ? \ # ! The command is terminated and
executed by typing a carriage return; to cancel a
partially typed command, type ESC to cancel the current
command and return to command mode.
ENVIRONMENT
The editor recognizes the environment variable BVIINIT as
a command (or list of commands) to run when it starts
up. If this variable is undefined, the editor checks for
startup commands in the file ~/.bvirc file, which you
must own. However, if there is a .bvirc owned by you in
the current directory, the editor takes its startup
commands from this file - overriding both the file in your
home directory and the environment variable.

COMMAND SUMMARY
See the TERMINOLOGY for a summary on key name
abbreviations used within the following description of
commands.
Abstract:
Arrow keys move the cursor on the screen within the
current window.
Sample commands:
:version show version info
<- v ^ -> arrow keys move the cursor
h j k l same as arrow keys
u undo previous change
ZZ exit bvi, saving changes
:q! quit, discarding changes
/text search for text
^U ^D scroll up or down
Counts before bvi commands:
Numbers may be typed as a prefix to some commands.
They are interpreted in one of these ways.
screen column |
byte of file G
scroll amount ^D ^U
repeat effect most of the rest
Interrupting, canceling
ESC end insert or incomplete command
DEL (delete or rubout) interrupts
File manipulation:
ZZ if file modified, write and exit;
otherwise, exit
:w write changed buffer to file
:w! write changed buffer to file, overriding
read-only ("forced" write)
:q quit when no changes have been made
:q! quit and discard all changes
:e file edit file
:e! reedit current file, discard all changes
:e # edit the alternate file
:e! # edit the alternate file, discard changes
:w file write current buffer to file
:w! file write current buffer to file overriding
read-only (this "overwrites" the file)
:sh run the command as set with option "shell",
then return
:!cmd run the command cmd from "shell", then
return
:n edit next file in the argument list
:f show current filename, modified flag,
current byte offset, and percentage of
current position within buffer
^G same as :f
Additional edit commands
You can insert/append/change bytes in
ASCII/binary/decimal/ hexadecimal or octal representation.
You can enter several (screen) lines of input. A line with
only a period (.) in it will terminate the command. You
must not type in values greater than a byte value. This
causes an abandom of the command. Pressing the CR key
does not insert a newline - character into the file. If
you use ASCII mode you can use the special characters \n,
\r, \t and \0.
:i aCR insert bytes (ASCII) at cursor position
:a bCR append bytes (Binary) at end of file
:c hCR change bytes (hexadecimal) at cursor position
Bit-level operations
:and n bitwise 'and' operation with value n
:or n bitwise 'or' operation with value n
:xor n bitwise 'xor' operation with value n
:neg two's complement
:not logical negation
:sl i shift each byte i bits to the left
:sr i shift each byte i bits to the right
:rl i rotate each byte i bits to the left
:rr i rotate each byte i bits to the right
Command mode addresses
:w foo write current buffer to a file
named "foo"
:5,10w foo copy byte 5 through 100 into as
file named foo
:.,.+20w foo copy the current byte and the next
20 bytes to foo
:^,'aw foo write all bytes from the beginning
through marker 'a'
:/pat/,$ foo search pattern pat and and copy
through end of file
Positioning within file:
^B backward screen
^F forward screen
^D scroll down half screen
^U scroll up half screen
nG go to the specified character
(end default), where n is a decimal address
/pat next line matching pat
?pat previous line matching pat
\hex jump to next occurrence of hex string hex
#hex jump to previous occurrence of hex string hex
n repeat last search command
N repeat last search command, but in opposite
direction
Adjusting the screen:
^L clear and redraw screen
zCR redraw screen with current line at top of screen
z- redraw screen with current line at bottom of
screen
z. redraw screen with current line at center of
screen
/pat/z- search for pattern pat and then move currents
line to bottom
^E scroll screen down 1 line
^Y scroll screen up 1 line
Marking and returning:
mx mark current position with lower-case letter x
Note: this command works for all lower-case
letters
'x move cursor to mark x in ASCII section
`x move cursor to mark x in HEX section
'' move cursor to previous context in ASCII section
`` move cursor to previous context in HEX section
Line positioning:
H jump to first line on screen ("top")
L jump to last line on screen ("low")
M jump to middle line on screen ("middle")
- jump onto previous line on screen
+ jump onto next line on screen
CR same as +
DOWN or j next line, same column
UP or k previous line, same column
Character positioning:
^ first byte in HEX window
$ end of screen line
l or RIGHT jump onto next byte (within current
screen line)
h or LEFT jump onto previous byte (within current
screen line)
^H same as LEFT
space same as RIGHT
fx find next occurrence of character x
Fx find previous occurrence of character x
n| jump onto nth byte/character within current
line
Strings:
(works similar to the strings(1) command)
Note: "Words" are defined as strings of "nonprinting
characters".
e jump to next end of word
w jump to next begin of word
b jump to previous begin of word
W forward to next string delimited with a
\0 or \n
B back to previous string delimited with a
nonprinting char
Corrections during insert:
^H erase last character (backspace)
erase your erase character, same as ^H (backspace)
ESC ends insertion, back to command mode
Append and replace:
A append at end of file
rx replace current bte with char 'x'
R enter replace mode; for all subsequent input,
the current byte is overwritten with the next
input character; leave replace mode with ESC.
Miscellaneous Operations:
TAB toggle between ASCII and HEX section
Yank and Put:
3ySPACE yank 3 characters
p insert contents of yank buffer
o replace text with content of yank buffer
P put back at end of file
Undo, Redo:
u undo last change
Note: Only the last change can be undone.
Therefore this commands toggles between the
last and second-t-last state of the buffer.
Setting Options:
With the :set command you can set options in bvi
Option Default Description
autowrite noaw Save current file, if modified, if you
give a :n, :r or ! command
columns cm=16 on an 80 character wide terminal

scroll sc=1/2 window
Number of lines scrolled by ^U and ^D
showmode mo Displays statusline on bottom of the screen
terse noterse Let you obtain shorter error messages
window window=screensize
Lines in window, can be reduced at slow terminals
wordlength wl=4 Length of an ASCII-string found by w, W, b or B
wrapscan ws Searches wrap around past the end of the file
unixstyle nous The representation of ascii characters below
32 is displayed in the statusline as shown

<UL>
<LI>Configuration with GNU autoconfig
<LI>New <B>:set</B> options:
<UL>
<LI><B>:set columns=n</B><BR>
You can set the number of columns on the screen to an
arbitrary value. This might be useful if you edit a file
with a fixed record length.<BR>
Default: max number of columns, divisible by four.<BR>
Abbreviation: <B>:set cm=n</B>
<LI><B>:set memmove</B>
enables the new commands to insert or delete bytes.<BR>
Per default this commands are disabled, because e.g. in
executable files you must not move bytes.<BR>
Default: <B>:set nomemmove</B><BR>
Abbreviation: <B>:set mm</B> - <B>:set nomm</B>
<LI>The listing for <B>:set all</B> is now in
alphabetical order.
</UL>
<LI>New insert and delete commands:
<UL>
<LI><B>a</B> inserts after cursor position
<LI><B>i</B> inserts on cursor position
<LI><B>x</B> deletes byte under cursor
<LI><B>X</B> deletes byte before cursor
<LI><B>d</B> delete command with modifiers:
<UL>
<LI><B>d<FONT COLOR=#888888>SPACE</FONT></B> deletes byte under cursor
<LI><B>df<FONT COLOR=#FF0000>C</FONT></B> deletes from current position to
next character <FONT COLOR=#FF0000>C</FONT>
<LI><B>d/<FONT COLOR=#FF0000>xyz</FONT></B> deletes from current position
to first matching pattern <FONT COLOR=#FF0000>xyz</FONT>
<LI><B>d$</B> deletes from current position to EOF
<LI><B>d'<FONT COLOR=#FF0000>a</FONT></B> deletes from current positions
to mark <FONT COLOR=#FF0000>a</FONT>
<LI><B>d<FONT COLOR=#FF0000>n</FONT>G</B> deletes from current position to
byte with (decimal) address <FONT COLOR=#FF0000>n</FONT>
</UL>
</UL>
<LI>New syntax for <B>p</B> (put) command:<BR>
In previous versions of <I>bvi</I> the <B>p</B> command did an overwriting
"put". Now the bytes are inserted.
<LI>New command <B>o</B> (overwrite):<BR>
This is an overwriting "put" command. It is the only command in <I>bvi</I>
that uses a command key in a complete different way than in <I>vi</I>
(<B>o</B> opens a new line in <I>vi</I>).
<LI>New syntax for <B>y</B> (yank) command:
<UL>
<LI><B>y<FONT COLOR=#888888>SPACE</FONT></B> yanks byte under cursor
<LI><B>yf<FONT COLOR=#FF0000>C</FONT></B> yanks from current position to next
character <FONT COLOR=#FF0000>C</FONT>
<LI><B>y/<FONT COLOR=#FF0000>xyz</FONT></B> yanks from current position to
first matching pattern <FONT COLOR=#FF0000>xyz</FONT>
<LI><B>y$</B> yanks from current position to EOF
<LI><B>y'<FONT COLOR=#FF0000>a</FONT></B> yanks from current position to
mark <FONT COLOR=#FF0000>a</FONT>
<LI><B>y<FONT COLOR=#FF0000>n</FONT>G</B> yanks from current position to
byte with (decimal) address <FONT COLOR=#FF0000>n</FONT>
</UL>
<LI>New ex (colon) commands:
<UL>
<LI><B>:a(ppend) a(scii)|b(binary)|d(ecimal)|h(exadecimal)|o(ctal)</B>
<LI><B>:c(hange) a(scii)|b(binary)|d(ecimal)|h(exadecimal)|o(ctal)</B>
<LI><B>:i(nsert) a(scii)|b(binary)|d(ecimal)|h(exadecimal)|o(ctal)</B><BR>
The three commands above are used to append or change or insert bytes
in the selected representation until you type a line containing only
a dot, e.g. insert bytes in binary mode:
<PRE>
:i b
0 010 110 1110010 10 100
1 1001 1001 0 0
.
</PRE>
Pressing the <FONT COLOR=#888888>RETURN</FONT> key does <I>not</I> insert
a newline - character into the file. If you use <B>:i a</B> (insert
ascii) you can use the special characters \n, \r, \t and \0.
<LI><B>:d(elete)</B>
<LI><B>:g(lobal)</B> does a global search with printing found items
<LI><B>:ma(rk)</B>
<LI><B>:pu(t)</B> puts yanked bytes into the file
<LI><B>:o(verwrite)</B> is an overwriting ":put"
<LI><B>:y(ank)</B>
</UL>
<LI><B>:f newname</B> - bug fixed
<LI>new command line option <B><TT>-f script</TT></B>
<LI><B>CTRL - C</B> aborts some commands, e.g. search commands
<LI>CR moves cursor to 1st column of next screen line
<LI>Local settings according to the environment variable LANG
will be evaluated (see setlocal(3)).

To perform logical operations, bvi has a set of bit-level commands.
The following commands are available:
<CENTER><TABLE>
<TR><TD><B>:rl </B><I>n</I></TD><TD>rotate left</TD><TD ROWSPAN=4>
<I>n</I> is a number from 1 through 7</TD></TR>
<TR><TD><B>:rr </B><I>n</I></TD><TD>rotate right</TD></TR>
<TR><TD><B>:sr </B><I>n</I></TD><TD>shift right</TD></TR>
<TR><TD><B>:sl </B><I>n</I></TD><TD>shift left</TD></TR>
<TR><TD><B>:and </B><I>i</I></TD><TD>and operation</TD><TD ROWSPAN=4>
<I>i</I> is a number from 0 through 255</TD></TR>
<TR><TD><B>:or </B><I>i</I></TD><TD>or operation</TD></TR>
<TR><TD><B>:xor </B><I>i</I></TD><TD>or operation</TD></TR>
<TR><TD><B>:not </B></TD><TD>negates operation</TD></TR>
<TR><TD><B>:neg </B></TD><TD>negates operation</TD></TR>
</TABLE></CENTER>
<P>
The <I>i</I> value can be entered as a decimal number (0 - 255),
a hexadecimal number with a leading zero (0 - 0ff) or a binary number,
either with a leading B (B101) or exactly eight digits long (00000101).
<P>
On default the whole file is affected, but you can use the usual
colon command address forms. In contrast to vi the addresses designate
not line numbers but byte numbers. These addresses can be enterd in
decimal or hexadecimal notation.<BR>
Examples:
<BLOCKQUOTE CLASS="examp">
<B><TT>:100,500and 01A </TT><FONT COLOR=#AAAAAA>RETURN</FONT></B><BR>
<B><TT>:03FA,01000or 00001000 </TT><FONT COLOR=#AAAAAA>RETURN</FONT></B><BR>

<p>
Inserting or deleting bytes can be dangerous on some kind of files,
because binary files are mostly executables, database files or maybe
graphic files. So you must not shift the remaining bytes to another
address.
Therefor commands for inserting or deleting bytes are disabled by
default.
You can use the <B>r</B> command to change a single byte, or
the <B>R</B> command to replace multiple characters. You can use a
numeric prefix for both commands.
<P>
You can add characters at the end of the file using the <B>A</B> command.
If you start with an empty file, you can create a binary file from
scratch. If the cursor is in the ASCII section of the screen and you
type <B><TT>100Ax</TT><FONT COLOR=#AAAAAA>ESC</FONT></B>, you create a file
which contents 100 x'es.
<P>
The <B>D</B> command can be used to truncate a file at a certain position.
Since there are no lines in a binary file, the <B>D</B> command deletes
to end of file.
<P>
If you have to edit a binary file where it does not matter to move bytes
to a different address, you can enable the insert and delete commands by
typing <B>:set memmove</B>.
Now you are able to use the <B>i</B> command for inserting bytes, the
<B>x</B> or <B>X</B> command to delete the byte over or before the cursor
and those types of <B>d</B> commands, which does not rely on text lines
(e.g. <B>d<FONT COLOR=#AAAAAA>SPACE</FONT></B>, <B>df<TT>C</TT>, d/<TT>xyz</TT>,
d$, d'a, d<TT>n</TT>G</B>).
<P>
All edits can be undone by pressing the <B>u</B> key.
<H4>Using ex (colon) commands</H4>
The edit commands of the <B>ex</B> editor are usually not available in
standard <B>vi</B> implementations (<TT>:i[nsert], :a[ppend]</TT>
and <TT>:c[hange]</TT>). In <B><FONT COLOR=#FF0000>bvi</B></FONT>
they <I>are</I> available with extended options. There are five
modifiers <TT>a[scii], b[inary], d[ecimal], h[exadecimal]</TT> and
<TT>o[ctal]</TT> (ascii is default). Therefor you can insert, append
or change data in all five representations.
<P>
<B>Example:</B><BR>
you would like to append a file with data available in decimal
representation:
<BLOCKQUOTE><PRE CLASS=examp>
:a d
0 12 3 128 255 17 0 0 255 255
23 24 25 128 6 6 6
.
</PRE></BLOCKQUOTE>
A line with only a period (.) in it will terminate the command.
<BR>
You must not type values greater than a byte value (255 decimal, FF hex).
This causes an abandon of the command.<BR>
Pressing the <FONT COLOR=#888888>RETURN</FONT> key does <I>not</I> insert
a newline - character into the file. If you use <B>:i a</B> (insert
ascii) you can use the special characters \n, \r, \t and \0.
<P>
An additional advantage is, that all typed bytes are inserted into the
file at once. If you insert characters in vi - mode, for every byte typed,
the whole remaining file has to be moved one position backwards.

<P>
Inserting or deleting bytes can be dangerous on some kind of files,
because binary files are mostly executables, database files or maybe
graphic files. So you must not shift the remaining bytes to another
address.
Therefor commands for inserting or deleting bytes are disabled by
default.
You can use the <B>r</B> command to change a single byte, or
the <B>R</B> command to replace multiple characters. You can use a
numeric prefix for both commands.
<P>
You can add characters at the end of the file using the <B>A</B> command.
If you start with an empty file, you can create a binary file from
scratch. If the cursor is in the ASCII section of the screen and you
type <B><TT>100Ax</TT><FONT COLOR=#AAAAAA>ESC</FONT></B>, you create a file
which contents 100 x'es.
<P>
The <B>D</B> command can be used to truncate a file at a certain position.
Since there are no lines in a binary file, the <B>D</B> command deletes
to end of file.
<P>
If you have to edit a binary file where it does not matter to move bytes
to a different address, you can enable the insert and delete commands by
typing <B>:set memmove</B>.
Now you are able to use the <B>i</B> command for inserting bytes, the
<B>x</B> or <B>X</B> command to delete the byte over or before the cursor
and those types of <B>d</B> commands, which does not rely on text lines
(e.g. <B>d<FONT COLOR=#AAAAAA>SPACE</FONT></B>, <B>df<TT>C</TT>, d/<TT>xyz</TT>,
d$, d'a, d<TT>n</TT>G</B>).
<P>
All edits can be undone by pressing the <B>u</B> key.
<H4>Using ex (colon) commands</H4>
The edit commands of the <B>ex</B> editor are usually not available in
standard <B>vi</B> implementations (<TT>:i[nsert], :a[ppend]</TT>
and <TT>:c[hange]</TT>). In <B><FONT COLOR=#FF0000>bvi</B></FONT>
they <I>are</I> available with extended options. There are five
modifiers <TT>a[scii], b[inary], d[ecimal], h[exadecimal]</TT> and
<TT>o[ctal]</TT> (ascii is default). Therefor you can insert, append
or change data in all five representations.
<P>
<B>Example:</B><BR>
you would like to append a file with data available in decimal
representation:
<BLOCKQUOTE><PRE>
:a d
0 12 3 128 255 17 0 0 255 255
23 24 25 128 6 6 6
.
</PRE></BLOCKQUOTE>
A line with only a period (.) in it will terminate the command.
<BR>
You must not type values greater than a byte value (255 decimal, FF hex).
This causes an abandon of the command.<BR>
Pressing the <FONT COLOR=#888888>RETURN</FONT> key does <I>not</I> insert
a newline - character into the file. If you use <B>:i a</B> (insert
ascii) you can use the special characters \n, \r, \t and \0.
<P>
An additional advantage is, that all typed bytes are inserted into the
file at once. If you insert characters in vi - mode, for every byte typed,
the whole remaining file has to be moved one position backwards.

<p>
The <B><TT CLASS="examp">:s</TT></B> (substitute) command behaves a little bit
different to that of vi. If you type a command like this in vi &nbsp; <NOBR>
<B><TT CLASS="examp">:s/XXXX/UU/</TT></B></NOBR> then the four XXXX's are
replaced by
two UU's. This means, the file size decreases and all characters after
the replacement are moved to another position in the file. Since bvi
does not move characters, only two XX's are replaced by two UU's and
the third and fourth X still remains in the file.<BR>
Another example:
<BLOCKQUOTE>
<B><TT CLASS="examp">:0,500s/Taste\0/Key\0/</TT><FONT COLOR=#AAAAAA>RETURN</FONT></B><BR>
</BLOCKQUOTE>
<P>
This command replaces within the first 500 bytes of a file the 0 -
terminated ASCII string &quot;<TT CLASS="examp">Taste</TT>&quot;
with the 0 - terminated
string &quot;<TT CLASS="examp">Key</TT>&quot;. After the substitution
you will find a
character sequence &quot;<TT CLASS="examp">Key\0e\0</TT>&quot; in the file.<BR>
CAUTION: If the replace
string is longer than the find string, additional bytes are overwritten!
<BR>
This behaviour will not be changed by setting the
<TT CLASS="examp">:set memmove</TT> option!
<P>
Of course you can do also binary substitutions, similar to the search
command. The ability of remembering patterns like <B><TT CLASS="examp">\(pattern\)</TT></B>
is currently not implemented.

A new feature of version 1.3.0 is the Partial File Read.
If you want to edit a file, you have not to read the file into
memory but only the part you want to edit. You can write back this part
into the file after editing.
<BR>
Example:
<BR>
You have to change only some bytes of the header of a graphic file
(e.g. a color). Graphic files can be very large. With the <TT>-s</TT>
option you can load only the first kilobyte of the file:
<PRE>
bvi -s 1000 large.gif
</PRE>
In this case of course you cannot insert or delete bytes of the file.
The editor is set to the <I>no memmove</I> mode. You can write back
only as much bytes as you read before. If you add or delete bytes
even though, the extra bytes will be ignored or garbage will be
written to the file.
<P>
It is also possible to start not at the begin of the file, but at a
certain address. To do this you have to use the option <TT>-b</TT>.
You can read the file from this starting point until the end of the file
or you can use the <TT>-s</TT> option to specify a size or the
<TT>-e</TT> option to specify an end address.
<P>
If you read the file not from the start an offset will be set to
display the correct address at the left side of the screen. If you change this
offset with the <TT>:set offset=<I>nnnn</I></TT> command, this has
<B>no</B> effect to the write back operation. The edited part of the
file will always be written back at the same position, where it was read.
<P>
In the Linux <TT>/proc</TT> directory there are files which are listed
with length 0 in a directory listing. But in reality they have a content.
You can read this files, if you use the <TT>-s</TT> option and guess a
size. This size should be a little bit larger than the size you expect.
<P>
The same guidlines can be used, if you load a block device, e.g. a
floppy disk.
<PRE>
bvi -s 1450k /dev/fd0
</PRE>
After reading the device, you get a message with the value of the
real read bytes at the bottom of the screen:
<PRE>
"/dev/fd0" range 0-1474559
</PRE>
Note that the <I>size</I> value will be used to allocate memory before
reading the file. Therefore do not choose a too large size.<BR>
Note further, that <I>1450k</I> in the example above is calculated as
<I>1450 * 1024</I> bytes. This gives <I>1484800</I> bytes allocated size.
If <STRONG>bvi</STRONG> reads the exact number of bytes you have asked for
in the <TT>-s</TT> option, the file may be larger.
<P>
<B>WARNING:</B>
<BLOCKQUOTE>
Do not use <STRONG>bvi</STRONG> at mounted disk devices!<BR>
Do not edit disk devices, if you don't know exactly what you change!<BR>
You may make your disk unreadable by editing it!!
</BLOCKQUOTE>
<H3>Interaction with <STRONG>bmore</STRONG></H3>
You may use <STRONG>bmore</STRONG> to browse through large files or
devices. You may use the ASCII - or Hex - search possibilities to
locate a certain section of the file.<BR>
If you see the desired part of the file on your screen, press <I><B>w</B></I> to
read the contents of the file displayed currently on your screen into
<STRONG>bvi</STRONG>. You can use a decimal prefix at the <I><B>w</B></I> -
command to read more or less bytes than displayed into <STRONG>bvi</STRONG>.
<BR>
The letter <I><B>w</B></I> is the next letter after <I><B>v</B></I>, which
is used in more and bmore to read the whole file into vi or bvi!
<P>
If you used the <TT>ZZ</TT> or <TT>:w</TT> command, this part of the file will be
written back into the original file.

<p>
Additional to the well known <B>/</B> and <B>?</B> for searching ASCII
strings there are two new commands for searching binary strings. These
are the keys <B>\</B> and <B>#</B>.
<P>
In the ASCII search commands <B>/</B> and <B>?</B> you can use \n, \r,
\t and \0. You can also use regular expressions. Do <I>not</I> use
<B>^</B> and <B>$</B>, because there are no lines in a binary file.
Type <B><TT>/foo\0</TT><FONT COLOR=#AAAAAA>RETURN</FONT></B> to
search for the null terminated string <I>foo</I> in the file.
<P>
In the Hex section you can search for a sequence of bytes in hexadecimal
notation, e.g. <NOBR><B><TT>\01 AF 12</TT><FONT COLOR=#AAAAAA>RETURN</FONT></B>,
</NOBR> which is the same as <NOBR><B><TT>\01AF12</TT><FONT COLOR=#AAAAAA>
RETURN</FONT></B></NOBR>.
You can also use regular expressions and quoted ASCII strings. Inside of
the quotes no character is treated as a special character!<BR>
Example: &nbsp;
<B><TT>\01 [^AF DE] "foo" 00 </TT><FONT COLOR=#AAAAAA>RETURN</FONT></B>
<BR>
This means: Search for a string beginning with 01, the second character
must not be a hex <TT>AF</TT> or <TT>DE</TT>, followed by the ASCII
characters <TT>foo</TT>, terminated with a binary zero.
<H3>Global Search</H3>
There is also a global search option available, but only with the
print option.<BR>
Example:
<BLOCKQUOTE>
<B><TT>:g/text_pattern/p</TT><FONT COLOR=#AAAAAA>RETURN</FONT></B>
<BR>or<BR>
<B><TT>:g\hex_pattern\p</TT><FONT COLOR=#AAAAAA>RETURN</FONT></B>
</BLOCKQUOTE>
This commands are displaying all found patterns, one per screen line.
Of course you can limit the search to a certain part of the file by
specifying the starting and ending address.<BR>
Other forms of the global search command
are line oriented, therefor <B>not</B> useful for binary files and
<B>not implemented</B>, e.g.<BR>
<BLOCKQUOTE>
<TABLE>
<TR><TD>:g/pattern/d</TD><TD>Delete all lines containing <I>pattern</I></TD></TR>
<TR><TD>:g/pattern/y</TD><TD>Yank all lines containing <I>pattern</I></TD></TR>

<H4>columns</H4>
<BLOCKQUOTE>
You can set the number of columns on the screen to an arbitrary value.
This might be useful if you edit a file with a fixed record length.<BR>
Default value is the max. number of columns, divisible by four.<BR>
Example: <B><TT>:set columns=13<FONT COLOR=#AAAAAA>RETURN</FONT></TT></B><BR>
Abbreviation: <B><TT>:set cm=9<FONT COLOR=#AAAAAA>RETURN</FONT></TT></B>

</BLOCKQUOTE>
<H4>offset</H4>
<BLOCKQUOTE>
You can change the beginning of the displayed byte numbering to a
certain number. The default address of the first byte is 0. You can
change it to 1 or to any other number by typing:<BR>
&nbsp; <B><TT>:set offset=1</TT><FONT COLOR=#AAAAAA>RETURN</FONT></B><BR>
You can also use a hexadecimal address, if you type a leading zero:<BR>
&nbsp; <B><TT>:set of=01FF</TT><FONT COLOR=#AAAAAA>RETURN</FONT></B><BR>
The only commands which are not affected by these numbering is
<TT><B>:f</B></TT> or <TT><B><FONT COLOR=#AAAAAA>CTRL</FONT>
-G</B></TT>. These commands always
designates the first byte in file as 1.
</BLOCKQUOTE>
<H4>unixstyle</H4>
<BLOCKQUOTE>
The rightmost character in the status line displays the ASCII value of
the current byte. For values below 32 you can use the notation used on
the ascii(7) man page (like NUL, SOH, STX etc.) if you do a<BR>
<B><TT>:set unixstyle<FONT COLOR=#AAAAAA>RETURN</FONT></TT></B> or a<BR>
<B><TT>:set us<FONT COLOR=#AAAAAA>RETURN</FONT></TT></B>. If you do a<BR>
<B><TT>:set nous<FONT COLOR=#AAAAAA>RETURN</FONT></TT></B> you get a
DOS style representation (^A, ^B, ^C etc.).
</BLOCKQUOTE>
<H4>wordlength</H4>
<BLOCKQUOTE>
This setting is used to define the minimum length of a &quot;word&quot;.
A &quot;word&quot; is a sequence of ASCII characters within a binary
file. The commands <B>w, b, e, W, B</B> and <B>E</B> are affected by
this setting.
<P>
Default: <B><TT>:set wordlength=4<FONT COLOR=#AAAAAA>RETURN</FONT></TT></B><BR>
Abbreviation: <B><TT>:set wl=4<FONT COLOR=#AAAAAA>RETURN</FONT></TT></B>

<H3>Using ex (colon) Commands</H3>
<B>:y</B>(ank)
<BLOCKQUOTE>
<I>yank</I> can be used with one or two addresses specified. One address
with no <I>count</I> specified copies the specified byte into the buffer.
Two addresses with no <I>count</I> specified copies multiple bytes
starting and ending with the specified bytes. Two addresses and a <I>count</I>
value copies <I>count</I> bytes starting at the second specified address (the
first address is ignored). If no address is specified, the current address
ist used by <I>yank</I>.<BR>
Examples:
<BLOCKQUOTE>
:<I>start_addr,end_addr</I> y <FONT COLOR=#888888>RETURN</FONT><BR>
:<I>start_addr</I> y <I>byte_count</I><FONT COLOR=#888888>RETURN</FONT><BR>
:y <I>byte_count</I><FONT COLOR=#888888>RETURN</FONT><BR>
</BLOCKQUOTE>
</BLOCKQUOTE>
<P>
<B>:pu</B>(t)
<BLOCKQUOTE>
Restores previously deleted or yanked bytes after the address specified
in the <I>put</I> command.
</BLOCKQUOTE>
<P>
<B>:o</B>(verwrite)
<BLOCKQUOTE>
Overwrites bytes after the specified address with previously deleted or yanked
bytes.
</BLOCKQUOTE>

This tutorial will explain all commands which behaves different to
vi. Note that, if you are on a Linux system, you will probably
have an 'improved' version of vi. Bvi is more similar to the standard
version.

The screen is divided into four areas, symbolized by four different
colors. The magenta area contents the addresses in hexadecimal
notation. The green area contents the values of the edited file in
hexadecimal notation. The red area contents the same bytes in ASCII
representation. The yellow status line displays on the left side the
current status messages and on the right site the current position
of the cursor and the value of the byte on this address in octal,
hexadecimal, decimal and ASCII notation.
<BR>
You can toggle between the Hex and ASCII value of the same byte by
pressing the <FONT COLOR=#AAAAAA><B>TAB</B></FONT> key both in command
and input mode.
<H3>Command Line Options</H3>
There are some additional command line options in <B>bvi</B>:<BR>
<BLOCKQUOTE>
<B><TT>-f <I>script</I></TT></B>
</BLOCKQUOTE>
This command provides a means for collecting a series of <I>ex</I>
(colon) commands into a script file, then using this file to edit
other files. Since there is no binary stream editor <I>bsed</I>, you
can use this option to make several global changes in a binary file.
You can do this of course with the <i>source</I> command (<B>:so file</B>)
from within bvi too.
<BLOCKQUOTE>
<B><TT>-b <I>begin</I></TT></B>
</BLOCKQUOTE>
This option causes bvi to load a file not from start but from address
<I>begin</I>.
<BLOCKQUOTE>
<B><TT>-e <I>end</I></TT></B>
</BLOCKQUOTE>
This option causes bvi to load a file not till end but till address
<I>end</I>.
<BLOCKQUOTE>
<B><TT>-s <I>size</I></TT></B>
</BLOCKQUOTE>
This option causes bvi not to load the complete file but only <I>size</I>
bytes. This option can also be used to read a file reported with a
length 0 like some files in the Linux <TT CLASS="examp">/proc</TT>
directory.
<P>
<I>begin, end</I> or <I>size</I> can be an integer value (decimal or
hexadecimal) or an integer value with an appended <B>k</B> (for
multiply by 1024) or <B>m</B> (for multiply by 1.048.576).
<P>
You should use at most two of the three address options to avoid ambiguity!
<H3>Not Implemented Commands</H3>
<P>
<UL>
<LI><B><TT>:map</TT></B> and <B><TT>:unmap</TT></B> (Macros)
<LI><B><TT>:abbreviate</TT></B> (<B><TT>:ab</TT></B>) and <B><TT>:una</TT></B>
<LI>no named buffers.
