I need to compare two binary files and get the output in the form <fileoffset-hex> <file1-byte-hex> <file2-byte-hex> for every different byte.

cmp is designed to find differences in binary files. You might also try checksumming ( sum ) and compare the hashes.

Calculating and storing a diff of the abc and abc2 files can be done with rsync. This is an example with abc and abc2 being 153 MB.

To compare subdirectories and any files they may contain as well, use diff -r. Combine it with -q to suppress the output for text files.

In this article, we'll talk about different ways to compare binary files in Linux. We may need this when investigating different files for ...

The diff command will compare two files for you, and highlight the differences. It can even provide a few lines on either side of the changes to provide some ...
