bspatch – apply a patch built with bsdiff(1)
bspatch oldfile newfile patchfile
The bspatch utility generates newfile from oldfile and patchfile where
patchfile is a binary patch built by bsdiff(1).
The bspatch utility uses memory equal to the size of oldfile plus the size
of newfile, but can tolerate a very small working set without a dramatic
loss of performance.
Colin Percival <cperciva@FreeBSD.org>
The bspatch utility does not verify that oldfile is the correct source file
for patchfile. Attempting to apply a patch to the wrong file will usually
produce garbage; consequently it is strongly recommended that users of
bspatch verify that oldfile matches the source file from which patchfile
was built, by comparing cryptographic hashes, for example. Users may also
wish to verify after running bspatch that newfile matches the target file
from which was built.
