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.
