BSDIFF(1) BSD General Commands Manual BSDIFF(1)NAME
bsdiff — generate a patch between two binary files
SYNOPSIS
bsdiff oldfile newfile patchfile
DESCRIPTION
The bsdiff utility compares oldfile to newfile and writes to patchfile a
binary patch suitable for use by bspatch(1). When oldfile and newfile
are two versions of an executable program, the patches produced are on
average a factor of five smaller than those produced by any other binary
patch tool known to the author.
The bsdiff utility uses memory equal to 17 times the size of oldfile, and
requires an absolute minimum working set size of 8 times the size of
oldfile.
