Hi, I was wondering if there was something floating out there in source land to essentially do a diff -e on an executable file...aka binary. Sorry I can't say why I need to do such a thing, but it sure helps in versioning things. The programs are in excess of 1 meg so I need something that takes less than a year to run! 8-) Any information is appreciated. John P.

You could try beav (Binary Editor And Viewer). Beav is a emacs like binary file editor that allows viewing data in many formats; hex, decimal, octal, binary, ascii, and ebcdic. There is a command that will compare the data in two windows and position the cursor at the first difference found. I posted the source to comp.sources.unix two months ago but it has not been released by the moderator. I posted an executable to comp.binaries.ibm.pc and it was archived at SIMTEL20. I posted an earlier version to alt.sources. -- >>>>>>>>>>>>>>>> Peter Reilley ..... pvr@wang.com <<<<<<<<<<<<<<<<<<<<<<< Well, that about says it.

Gnu-diff available from prep.ai.mit.edu:/gnu/diff may do what you want.
It does have the
capability to diff binary files (you might want to do a diff -ae).
