Can you use diff on binary files?

How does Bsdiff work?

A traditional diff update to a file (using bsdiff) works like this: the old file and the patch file are read into memory. Next, a patch operation is performed in memory, resulting in the new file being in memory. Finally, the new file is written to disk. We modify that operation slightly.

Can git be used for binary files?

Git LFS is a Git extension used to manage large files and binary files in a separate Git repository. Most projects today have both code and binary assets.

What is a xxd file?

Like uuencode(1) and uudecode(1) it allows the transmission of binary data in a ‘mail-safe’ ASCII representation, but has the advantage of decoding to standard output.

What does xxd stand for Linux?

Run this script on your two input files. Then run ‘diff -au file1 file2 > mod.diff (you will get the patch here)’
