Madsen [% ELSE %] vbindiff - hexadecimal file display and comparison [% END %] =head1 SYNOPSIS B I [ I ] =head1 DESCRIPTION Visual Binary Diff (VBinDiff) displays files in hexadecimal and ASCII (or EBCDIC). It can also display two files at once, and highlight the differences between them. Unlike B, it works well with large files (up to 4 GB). =head2 Viewing files Movement Keys ------------- Up Move one line (16 bytes) towards the beginning of the file Down Move one line (16 bytes) towards the end of the file Left Move one byte towards the beginning of the file Right Move one byte towards the end of the file PageUp Move one page towards the beginning of the file PageDn Move one page towards the end of the file Home Move to the beginning of the file End Move to the end of the (shorter) file F Search for a string or byte sequence G Move to a specified file position When displaying two files, both files move together. If bytes have been added or removed in one of the files, you can adjust the comparison by moving just one of the files. [% IF Win32 %] Holding down Alt while using the movement keys will scroll only the bottom file. Holding down Ctrl will scroll only the top file. [% ELSE %] To move only the top file, press C. To move only the bottom file, press C. To return to moving both files, press the same key again. (The window at the bottom of the screen will indicate when you are moving only one file.) [% END %] Other Keys ---------- Enter Move to the next difference between the files Space (same as Enter) C Toggle between ASCII and EBCDIC display E Edit currently displayed section of file Esc Exit VBinDiff Q Exit VBinDiff The C key will advance to the next difference between the files (after those already displayed on the screen). If there are no more differences, it moves to the end. =head2 Line editor The line editor is used to enter search strings and file positions. It uses the basic Emacs-style editing keys. Keys ----------------- Ctrl-B, Left Move the cursor one character left Ctrl-F, Right Move the cursor one character right Ctrl-A, Home Move to the beginning of the line Ctrl-E, End Move to the end of the line Ctrl-P, Up Move up in input history Ctrl-N, Down Move down in input history Ctrl-H, Backspace Delete the character to the left Ctrl-D, Delete Delete the character under the cursor Ctrl-K Delete from cursor to end of line Insert Toggle between insert & overstrike mode Enter Finished entering text Esc Abort the operation =head2 Editing files You can press C to edit the current file. When displaying two files, this edits the one in the top window[% IF Win32 %] . Press C to edit the file in the bottom window. [% ELSE %] , unless you are in "move bottom" mode. [% END %] When editing, you can move the cursor around with the arrow keys. Use TAB to switch between entering hexadecimal or ASCII (or EBCDIC) characters. Press the Esc key when you are done. You will be given the choice to save or discard your changes then. If you are displaying two files, you can use the Enter key to copy a byte from the other file into the one you are editing. You cannot scroll through the file while editing, although you can save your changes and then move to a different part of the file. Also, you cannot insert or delete bytes, only change them. =head1 OPTIONS -L, --license Display license information for vbindiff -V, --version Display the version number --help Display help information =head1 BUGS Does not work properly with files over 4 gigabytes. It should be able to view the first 4 gigabytes ok, but the display only has room for 8 hex digits of file position, and the Goto box is also limited to 8 digits. =head1 LICENSE VBinDiff 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.

It can also display two files at once, and highlight the differences between them. Unlike diff, it works well with large files (up to 4 GB). VBinDiff was inspired by the Compare Files function of the ProSel utilities by Glen Bredon, for the Apple II. When I couldn't find a similar utility for the PC, I wrote it myself. The single-file mode was inspired by the LIST utility of 4DOS and friends (http://www.jpsoft.com/4ntdes.htm). While less (http://www.greenwoodsoftware.com/less/) provides a good line-oriented display, it has no equivalent to LIST's hex display. (True, you can pipe the file through hexdump, but that's incredibly inefficient on multi-gigabyte files.) [% section('System Requirements') %] Windows 95, Windows NT 4.0, or later or A POSIX-compatible system with ncurses (eg, Linux) It should be possible to port the ncurses version to work with other curses libraries (as long as they provide the panel library), but I don't have access to such a system. Patches are welcome. [% section('Installation') %] [% IF Win32 %] Copy VBinDiff.exe to a folder on your path. If you don't know what a path is, you can put it in your C:\Windows directory. Then read VBinDiff.txt to find out how to use it. [% ELSE %] VBinDiff uses the standard GNU autoconf system. See the file INSTALL if you're not familiar with that. [% END %] [% IF Win32 %] [% section('Removal') %] To remove VBinDiff, just delete it. It makes no registry changes or INI files.

Madsen CONTENTS ======== [1] About Visual Binary Diff [2] System Requirements [3] Installation [4] License [5] Author [1] About Visual Binary Diff ---------------------------- Visual Binary Diff (VBinDiff) displays files in hexadecimal and ASCII (or EBCDIC). It can also display two files at once, and highlight the differences between them. Unlike diff, it works well with large files (up to 4 GB). VBinDiff was inspired by the Compare Files function of the ProSel utilities by Glen Bredon, for the Apple II. When I couldn't find a similar utility for the PC, I wrote it myself. The single-file mode was inspired by the LIST utility of 4DOS and friends (http://www.jpsoft.com/4ntdes.htm). While less (http://www.greenwoodsoftware.com/less/) provides a good line-oriented display, it has no equivalent to LIST's hex display. (True, you can pipe the file through hexdump, but that's incredibly inefficient on multi-gigabyte files.) [2] System Requirements ----------------------- Windows 95, Windows NT 4.0, or later or A POSIX-compatible system with ncurses (eg, Linux) It should be possible to port the ncurses version to work with other curses libraries (as long as they provide the panel library), but I don't have access to such a system. Patches are welcome. [3] Installation ---------------- VBinDiff uses the standard GNU autoconf system. See the file INSTALL if you're not familiar with that.

In other projects, it is set to # `$srcdir', `$srcdir/..', or `$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Madsen" .SH "NAME" vbindiff \- hexadecimal file display and comparison .SH "SYNOPSIS" .IX Header "SYNOPSIS" \&\fBvbindiff\fR \fIfile1\fR [ \fIfile2\fR ] .SH "DESCRIPTION" .IX Header "DESCRIPTION" Visual Binary Diff (VBinDiff) displays files in hexadecimal and \s-1ASCII\s0 (or \s-1EBCDIC\s0). It can also display two files at once, and highlight the differences between them. Unlike \fBdiff\fR, it works well with large files (up to 4 \s-1GB\s0). .Sh "Viewing files" .IX Subsection "Viewing files" .Vb 12 \& Movement Keys \& ------------- \& Up Move one line (16 bytes) towards the beginning of the file \& Down Move one line (16 bytes) towards the end of the file \& Left Move one byte towards the beginning of the file \& Right Move one byte towards the end of the file \& PageUp Move one page towards the beginning of the file \& PageDn Move one page towards the end of the file \& Home Move to the beginning of the file \& End Move to the end of the (shorter) file \& F Search for a string or byte sequence \& G Move to a specified file position .Ve .PP When displaying two files, both files move together. If bytes have been added or removed in one of the files, you can adjust the comparison by moving just one of the files. To move only the top file, press \f(CW\*(C`T\*(C'\fR. To move only the bottom file, press \f(CW\*(C`B\*(C'\fR. To return to moving both files, press the same key again. (The window at the bottom of the screen will indicate when you are moving only one file.) .PP .Vb 8 \& Other Keys \& ---------- \& Enter Move to the next difference between the files \& Space (same as Enter) \& C Toggle between ASCII and EBCDIC display \& E Edit currently displayed section of file \& Esc Exit VBinDiff \& Q Exit VBinDiff .Ve .PP The \f(CW\*(C`Enter\*(C'\fR key will advance to the next difference between the files (after those already displayed on the screen). If there are no more differences, it moves to the end. .Sh "Line editor" .IX Subsection "Line editor" The line editor is used to enter search strings and file positions. It uses the basic Emacs-style editing keys. .PP .Vb 14 \& Keys \& ----------------- \& Ctrl-B, Left Move the cursor one character left \& Ctrl-F, Right Move the cursor one character right \& Ctrl-A, Home Move to the beginning of the line \& Ctrl-E, End Move to the end of the line \& Ctrl-P, Up Move up in input history \& Ctrl-N, Down Move down in input history \& Ctrl-H, Backspace Delete the character to the left \& Ctrl-D, Delete Delete the character under the cursor \& Ctrl-K Delete from cursor to end of line \& Insert Toggle between insert & overstrike mode \& Enter Finished entering text \& Esc Abort the operation .Ve .Sh "Editing files" .IX Subsection "Editing files" You can press \f(CW\*(C`E\*(C'\fR to edit the current file. When displaying two files, this edits the one in the top window, unless you are in \*(L"move bottom\*(R" mode. .PP When editing, you can move the cursor around with the arrow keys. Use \&\s-1TAB\s0 to switch between entering hexadecimal or \s-1ASCII\s0 (or \s-1EBCDIC\s0) characters. Press the Esc key when you are done. You will be given the choice to save or discard your changes then. .PP If you are displaying two files, you can use the Enter key to copy a byte from the other file into the one you are editing. .PP You cannot scroll through the file while editing, although you can save your changes and then move to a different part of the file. Also, you cannot insert or delete bytes, only change them. .SH "OPTIONS" .IX Header "OPTIONS" .Vb 3 \& -L, --license Display license information for vbindiff \& -V, --version Display the version number \& --help Display help information .Ve .SH "BUGS" .IX Header "BUGS" Does not work properly with files over 4 gigabytes. It should be able to view the first 4 gigabytes ok, but the display only has room for 8 hex digits of file position, and the Goto box is also limited to 8 digits. .SH "LICENSE" .IX Header "LICENSE" VBinDiff is free software; you can redistribute it and/or modify it under the terms of the \s-1GNU\s0 General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. .PP VBinDiff is distributed in the hope that it will be useful, but \&\s-1WITHOUT\s0 \s-1ANY\s0 \s-1WARRANTY\s0; without even the implied warranty of \&\s-1MERCHANTABILITY\s0 or \s-1FITNESS\s0 \s-1FOR\s0 A \s-1PARTICULAR\s0 \s-1PURPOSE\s0.

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.

END OF TERMS AND CONDITIONS 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.

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.

But its xterm emulation is not completely accurate, and it so happens that VBinDiff triggers the problem. When using VBinDiff with the "xterm" terminal type, you'll notice that the background color doesn't extend to the right edge of the screen. (Also, the Home and End keys don't work.) To fix this, you must tell PuTTY to stop pretending it's an xterm. To do that, go to the PuTTY Configuration dialog, and find the Data page (under Connection). Change the Terminal-type string from "xterm" to "putty". Don't forget to save your settings after making this change. This brings us to the second problem. The terminal description for PuTTY distributed with ncurses 5.4 misidentifies the Home and End keys as Find and Select, respectively. That means those keys won't work in VBinDiff (or other programs, for that matter). To fix this, you can get the latest terminfo file from the author of ncurses (Thomas Dickey) and install it: ftp://invisible-island.net/ncurses/terminfo.src.gz Or, for your convenience, I have included the corrected terminfo record with VBinDiff in the file putty.src. To install it (on the system running VBinDiff), simply type: tic putty.src If you do that as root, it will update the system terminfo database with the corrected record. Otherwise, it will install the record in your home directory (under ~/.terminfo).
