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. + + + Copyright (C) 19yy + + 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. + + , 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. diff --git a/CREDITS b/CREDITS new file mode 100644 index 0000000..011a17d --- /dev/null +++ b/CREDITS @@ -0,0 +1,18 @@ +Patches: +Guido sys_errlist +Christian "naddy" Weisgerber {Free,Open}BSD +Gunnar Larisch ^ZZ bug +Peter J.

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.

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.

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.

+bmore 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 --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 characters 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 commands 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). +

+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.
+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. :set offset=256), this offset has to be +added to the byte addresses.
+Without an address, the whole file is affected or the current cursor +position is used (depending of the command). +

+Deutsche Beschreibung + + +BVI +
+
+
+ +

+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). + +

Zusätzliche Kommandos

+ +Eine wichtige Funktion für binäre Files ist das Suchen nach Hexcodes. +Dafür gibt es analog zum '/' und '?' - Kommando zusätzlich das '\' und +das '#' - Kommando.
+ +Beispiel:
+\1e f4 56 - Sucht die angegebene Bytefolge in vorwärts-Richtung
+#34 5a a4 - Sucht Bytefolge rückwärts. +

+Die normalen Textsuchkommandos sind auch vorhanden, wobei zusätzlich ein +Return, Linefeed oder NULL im Suchstring aufscheinen darf (\n \r oder \0). +

+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. +

+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. +

+ +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. + +

Regular Expressions

+ +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. + +

Zeilen

+ +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. + +

Editierkommandos

+ +Da binäre Files häufig ausführbare Programme oder Datenbankfiles sind, +bei denen Bytes nicht einfach an eine andere Adresse verschoben werden +dürfen, sind Einfüge- und Löschkommandos (z.B. a, i, x) +deaktiviert. Mit dem Kommando :set memmove können sie +aktiviert werden. +

+Die Kommandos :a (append), :c (change) und :i (insert) +können benutzt werden, um ein oder mehrere Bytes in ASCII, binärer, +dezimaler, hexadezimaler oder oktaler Schreibweise einzugeben +(a, b, d, h oder o). Es +können mehrere (Bildschirm) Zeilen eingegeben werden. Das Kommando +wird beendet, sobald eine Zeile, die nur aus einem Punkt besteht, +eingegeben wird. +

+Beispiel: +

+
+:i b
+1 1001 010101 1111
+11111 1010 1 0 1
+.
+
+
+Zu beachten ist, daß kein Einzelwert den maximalen Byte-Wert (255) +überschreiten darf, da sonst die Eingabe abgebrochen wird. Das +Drücken der RETURN - Taste führt zu keinem "RETURN" - Zeichen in +der Datei, im ASCII - Modus können allerdings die Sonderzeichen +\n, \r, \t und \0 benutzt werden. + +

Yank und Put

+ +Auch hier gilt eine etwas geänderte Funktion. Das y (yank) - +Kommando ist allerdings ab Version 1.2.0 dem Vi angenähert:
+ + + + + +
5ySPACEkopiert 5 Zeichen in den Yank-Buffer
oüberschreibt an Cursor - Position die folgenden Zeichen +mit dem Inhalt des Yank- oder Delete - Puffers
pfügt an der Cursor - Position den Inhalt des Yank- +oder Delete - Puffers ein.
Pfügt den Inhalt des Yank- oder Delete - Puffers am Dateiendes +an.
+

+Das Kommando ":r filename" fügt das angegebene File nicht an der Cursor- +Position sondern am Dateiende an. + +

Adressen

+ +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.
+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. + +

Bitweise Kommandos

+ +Um Manipulationen auf Bit-Ebene durchführen zu können, stehen +folgende Kommandos zur Verfügung: +
+ + + + + + + + + +
:rl nRotiert Bits links + n ist eine Zahl zwischen 1 und 7
:rr nRotiert Bits rechts
:sl nSchiebt Bits links
:sr nSchiebt Bits rechts
:and iUnd Verknüpfung + i ist eine Zahl zwischen 0 und 255
:or iOder Verknüpfung
:xor iExklusiv-oder Verknüpfung
:not Negiert Bytewert
:neg Zweier-Komplement
+Wird kein Bereich angegeben, so bezieht sich die Operation auf die gesamte +Datei. Es können zwei Adressen in den üblichen Schreibweisen +angegeben werden. Normalerweise wird dezimale Eingabe erwartet, bei +führender 0 werden die Adressen Hexadezimal interpretiert. +
Der Wert i für die logische Verknüpfung kann +dezimal, hexadezimal, oder mit führendem B in binärer +Schreibweise angegeben werden. Auch bei Eingabe von genau acht 0 und 1 +Werten wird der Byte - Wert binär interpretiert.
+Beispiel:
+
+:100,500and 01A RETURN
+:03FA,01000or 00001000 RETURN
+:.rr 3 RETURN
+:'a,$sl 1 RETURN

    +    # gunzip -c bvi-1.3.0.src.tar.gz | tar xvf
+
    +
  3. Change to the directory bvi-1.3.0 and type +
    +    # ./configure
+    # make
+
    + +
  4. Type `make install' for copying the executable files +and manual pages to the final directories. +
    +By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. +You can specify an +installation prefix other than `/usr/local' by giving +`configure' the option +`--prefix=PATH'. Use the +`--with-ncurses' option to configure to specify an +alternate search path for Ncurses outside the normal +include/lib search path. +

    +You will find now four new commands: +

    +    bvi     The binary editor
+    bview   The readonly version of bvi
+    bedit   The beginners version of bvi
+    bmore   The binary more program
+
    +
  5. Use `make uninstall' to remove the installed +files from your file system.
    +You can remove the program binaries and object files from the +source code directory by typing `make clean'. +To also remove the files that `configure' created +(so you can compile the package for +a different kind of computer), type `make distclean'. +
+ +

MSDOS

+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'. +

+The MSDOS version is using the conio routines of the +Borland - C compilers for cursor movement. The doscur.h +header file substitutes the curses commands.
+Bvi is using the "HUGE" memory model, bmore +needs the "TINY" model to +be able to convert it to a .COM file. + +

    +
  1. Download the source package from the Download Page +
  2. Unzip the package with the command: +
    +    gunzip -c bvi-1.3.0.src.tar.gz | tar xvf
+
    +
  3. Load the tcconfig file (located in the bc subdirectory +for Borland - C). + +
  4. Press F9-Make +

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. + +TERMINOLOGY + Characters names are abbreviated as follows: + Abbr.

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

  • A make uninstall option has been added +

    +

  • A bmore program has been added. It acts like the BSD - text - more, +but for binary files.

    +Additional command line options: +

    +-a   ASCII mode +
    +Additional (changed) Commands: +
    +v   does not invoke vi but bvi
    +w   invokes bvi with only that portion of the file +which is displayed on the screen. +
    +
  • New in bvi: +
      +
    • You can edit now Block Special Files too. +
    • You can read - edit - write files partly. +
    • New Command line options: +

+This overview compares bvi commands with the corresponding commands of +the standard ascii vi. +

+

+ + + + +
Commands shown in blue frames are commands which +are available in both bvi and vi, but with a slightly different +behavior.
Green frames are used for commands which are +equal in both bvi and vi.
Red frames are used for missing commands
+
+

+Special keys are displayed in a gray font, e.g. +RETURN, +ARROW_UP or +CTRL. + +

Bit-wise Operations +		 + +BVI +
+
+
+ +

+To perform logical operations, bvi has a set of bit-level commands. +The following commands are available: +

+ + + + + + + + + +
:rl nrotate left + n is a number from 1 through 7
:rr nrotate right
:sr nshift right
:sl nshift left
:and iand operation + i is a number from 0 through 255
:or ior operation
:xor ior operation
:not negates operation
:neg negates operation
+

+The 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). +

+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.
+Examples: +

+:100,500and 01A RETURN
+:03FA,01000or 00001000 RETURN
+:.rr 3 RETURN
+:'a,$sl 1 RETURN

+
+ +

+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 r command to change a single byte, or +the R command to replace multiple characters. You can use a +numeric prefix for both commands. +

+You can add characters at the end of the file using the A 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 100AxESC, you create a file +which contents 100 x'es. +

+The D command can be used to truncate a file at a certain position. +Since there are no lines in a binary file, the D command deletes +to end of file. +

+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 :set memmove. +Now you are able to use the i command for inserting bytes, the +x or X command to delete the byte over or before the cursor +and those types of d commands, which does not rely on text lines +(e.g. dSPACE, dfC, d/xyz, +d$, d'a, dnG). + +

+All edits can be undone by pressing the u key. +

Using ex (colon) commands

+The edit commands of the ex editor are usually not available in +standard vi implementations (:i[nsert], :a[ppend] +and :c[hange]). In bvi +they are available with extended options. There are five +modifiers a[scii], b[inary], d[ecimal], h[exadecimal] and +o[ctal] (ascii is default). Therefor you can insert, append +or change data in all five representations. +

+Example:
+you would like to append a file with data available in decimal +representation: +

+:a d
+0 12 3 128 255 17 0 0 255 255
+23 24 25 128 6 6 6
+.
+
+A line with only a period (.) in it will terminate the command. +
+You must not type values greater than a byte value (255 decimal, FF hex). +This causes an abandon of the command.
+Pressing the RETURN key does not insert +a newline - character into the file. If you use :i a (insert +ascii) you can use the special characters \n, \r, \t and \0. +

+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. +

Find and Replace +		 + +BVI +
+
+
+ +

+The :s (substitute) command behaves a little bit +different to that of vi. If you type a command like this in vi   +:s/XXXX/UU/ 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.
+Another example: +

+:0,500s/Taste\0/Key\0/RETURN
+
+

+This command replaces within the first 500 bytes of a file the 0 - +terminated ASCII string "Taste" +with the 0 - terminated +string "Key". After the substitution +you will find a +character sequence "Key\0e\0" in the file.
+CAUTION: If the replace +string is longer than the find string, additional bytes are overwritten! +
+This behaviour will not be changed by setting the +:set memmove option! +

+Of course you can do also binary substitutions, similar to the search +command. The ability of remembering patterns like \(pattern\) +is currently not implemented. +

+Quick Tutorial +
Partial File Read +		 + +BVI +
+
+
+ +

+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. +
+Example: +
+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 -s +option you can load only the first kilobyte of the file: +

+             bvi -s 1000 large.gif
+
+In this case of course you cannot insert or delete bytes of the file. +The editor is set to the no memmove 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. +

+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 -b. +You can read the file from this starting point until the end of the file +or you can use the -s option to specify a size or the +-e option to specify an end address. +

+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 :set offset=nnnn command, this has +no 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. +

+In the Linux /proc 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 -s option and guess a +size. This size should be a little bit larger than the size you expect. +

+The same guidlines can be used, if you load a block device, e.g. a +floppy disk. +

+             bvi -s 1450k /dev/fd0
+
+After reading the device, you get a message with the value of the +real read bytes at the bottom of the screen: +
+             "/dev/fd0" range 0-1474559
+
+Note that the size value will be used to allocate memory before +reading the file. Therefore do not choose a too large size.
+Note further, that 1450k in the example above is calculated as +1450 * 1024 bytes. This gives 1484800 bytes allocated size. +If bvi reads the exact number of bytes you have asked for +in the -s option, the file may be larger. +

+WARNING: +

+Do not use bvi at mounted disk devices!
+Do not edit disk devices, if you don't know exactly what you change!
+You may make your disk unreadable by editing it!! +
+

Interaction with bmore

+You may use bmore to browse through large files or +devices. You may use the ASCII - or Hex - search possibilities to +locate a certain section of the file.
+If you see the desired part of the file on your screen, press w to +read the contents of the file displayed currently on your screen into +bvi. You can use a decimal prefix at the w - +command to read more or less bytes than displayed into bvi. +
+The letter w is the next letter after v, which +is used in more and bmore to read the whole file into vi or bvi! +

+If you used the ZZ or :w command, this part of the file will be +written back into the original file. + +

Search Commands +		 + +BVI +
+
+
+ +

+Additional to the well known / and ? for searching ASCII +strings there are two new commands for searching binary strings. These +are the keys \ and #. +

+In the ASCII search commands / and ? you can use \n, \r, +\t and \0. You can also use regular expressions. Do not use +^ and $, because there are no lines in a binary file. +Type /foo\0RETURN to +search for the null terminated string foo in the file. +

+In the Hex section you can search for a sequence of bytes in hexadecimal +notation, e.g. \01 AF 12RETURN, + which is the same as \01AF12 +RETURN. +You can also use regular expressions and quoted ASCII strings. Inside of +the quotes no character is treated as a special character!
+Example:   +\01 [^AF DE] "foo" 00 RETURN +
+This means: Search for a string beginning with 01, the second character +must not be a hex AF or DE, followed by the ASCII +characters foo, terminated with a binary zero. + +

Global Search

+There is also a global search option available, but only with the +print option.
+Example: +
+:g/text_pattern/pRETURN +
or
+:g\hex_pattern\pRETURN +
+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.
+Other forms of the global search command +are line oriented, therefor not useful for binary files and +not implemented, e.g.
+
+ + + + +
:g/pattern/dDelete all lines containing pattern
:g/pattern/yYank all lines containing pattern
:g!/pattern/pPrint all lines not containing pattern

+To customize bvi some additional :set options are +available. You can add them to your .bvirc +file, if you need them all the time. + +

columns

+
+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.
+Default value is the max. number of columns, divisible by four.
+Example: :set columns=13RETURN
+Abbreviation: :set cm=9RETURN +
+ +

memmove

+
+This option enables the commands for inserting and deleting bytes. +
+Default: :set nomemmoveRETURN
+Abbreviation: :set mmRETURN +
+ +

offset

+
+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:
+  :set offset=1RETURN
+You can also use a hexadecimal address, if you type a leading zero:
+  :set of=01FFRETURN
+The only commands which are not affected by these numbering is +:f or CTRL +-G. These commands always +designates the first byte in file as 1. +
+ +

unixstyle

+
+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
+:set unixstyleRETURN or a
+:set usRETURN. If you do a
+:set nousRETURN you get a +DOS style representation (^A, ^B, ^C etc.). +
+ +

wordlength

+
+This setting is used to define the minimum length of a "word". +A "word" is a sequence of ASCII characters within a binary +file. The commands w, b, e, W, B and E are affected by +this setting. +

+Default: :set wordlength=4RETURN
+Abbreviation: :set wl=4RETURN +

Yank and Put +		 + +BVI +
+
+
+ +

+Starting with version 1.2.0 there is a new syntax for the yank and put +commands! Yank is now more similare to vi. +

+ + + + + + + + + + + + + + + + + + +
ySPACEyanks byte under cursor
nySPACE + yanks n bytes, beginning at cursor + position
yfCyanks from current position to next + character C
y/xyzyanks from current position to first matching + pattern xyz
y$yanks from current position to EOF
y'ayanks from current position to mark a
ynGyanks from current position to byte with (decimal) + address n
ooverwrites the bytes after the cursor with the contents of the yank + or delete buffer
pputs the contents of the yank or delete + buffer after the cursor
Pappends the contents of the buffer to end + of file
+ +

Using ex (colon) Commands

+:y(ank) +
+yank can be used with one or two addresses specified. One address +with no count specified copies the specified byte into the buffer. +Two addresses with no count specified copies multiple bytes +starting and ending with the specified bytes. Two addresses and a count +value copies count bytes starting at the second specified address (the +first address is ignored). If no address is specified, the current address +ist used by yank.
+Examples: +
+ :start_addr,end_addr y RETURN
+ :start_addr y byte_countRETURN
+ :y byte_countRETURN
+
+
+

+:pu(t) +

+Restores previously deleted or yanked bytes after the address specified +in the put command. +
+

+:o(verwrite) +

+Overwrites bytes after the specified address with previously deleted or yanked +bytes. +
+

+NOTE: There are currently no namend buffers available. +

+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. +
+You can toggle between the Hex and ASCII value of the same byte by +pressing the TAB key both in command +and input mode. + +

Command Line Options

+There are some additional command line options in bvi:
+ +
+-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. +You can do this of course with the source command (:so file) +from within bvi too. + +
+-b begin +
+This option causes bvi to load a file not from start but from address +begin. + +
+-e end +
+This option causes bvi to load a file not till end but till address +end. + +
+-s size +
+This option causes bvi not to load the complete file but only size +bytes. This option can also be used to read a file reported with a +length 0 like some files in the Linux /proc +directory. +

+begin, end or size can be an integer value (decimal or +hexadecimal) or an integer value with an appended k (for +multiply by 1024) or m (for multiply by 1.048.576). +

+You should use at most two of the three address options to avoid ambiguity! + + +

settings		 + + + + + + + +
:set wrapscan or :set ws
+ :set nows		When this option is set, pattern searches resulting from a /, + ?, n, N (#, \) command automatically wrap around to the opposit end of the file + and continue whenever the beginning or end of a file is reached.
:set ignorecase or :set ic
+ :set noic		Uppercase and lowercase characters in text are treated identically + in regular expression matching
:set magic
+ :set nomagic		Enables metacharacters for use in regular expressions
+
Display
options		 + + + + + +
:set showmode
+ :set noshowmode		Displays a status message in the lowest line on the screen
:set terse
+ :set noterse		The terse option lets you obtain shorter error diagnostics.
+
File
options		 + + + + + +
:set readonly or :set ro
+ :set noro		This option sets the read-only flag for the file being editeds, + thus preventing accidental overwriting at the end of the session.
:set autowrite or :set aw
+ :set noaw		Causes the contents of the buffer to be written to the current file + if you have modified them and given a :next, :rewind or ! + command.
+
bvi
options		 + + + + + + + + + + + +
:set columns=13
:set cm=5		You can set the number of bytes displayed in on screenline. + Default is max. number divisible by four.
:set memmove
:set nomm		If memmove is set, you can use commands to insert or delete bytes. + This can be dangerous for e.g. executable programs. + Default is nomemmove.
:set offset=1
:set of=5		An offset is added to all addresses and byte counts. Default + address of the first byte is 0.
:set wordlength=5
:set wl=8		Length of an ASCII-string found by w, W, b or B
:set unixstyle
:set nous		displays ASCII characters below 32 in the status line in + Unix-style instead of DOS-style
