bsdiff

generate/apply a patch between two binary files

NAME

bsdiff - generate a patch between two binary files

SYNOPSIS

bsdiff <oldfile<newfile<patchfile>>>

DESCRIPTION

bsdiff 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.
bsdiff 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.
