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.
