I have an application that in effect copies a file and it is sometimes failing to faithfully copy it for some 20MB test files. I would like to compare the original file to the corrupted ones to see if I can identify any patterns to help me correct the bug in my application. The files are the exact same length.

What is a tool I can run on Centos 4 or 5 that will let me see the differences between these two files at a byte by byte level. I expect the difference is very small, such as a messed up bit somewhere in the file and I would like to fine the differences and their offset from the beginning of the file. The built in Unix diff utility only says they differ when given binary files.
