BSDIFF(1) General Commands Manual BSDIFF(1) 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 bi- nary patch suitable for use by bspatch(1). When <oldfile> and <newfile> are two versions of an executable program, the patches pro- duced 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 re- quires an absolute minimum working set size of 8 times the size of old- file.
