That command works just fine for me with the file you attached. That is, this command:

fgrep -x -f dfba.py dfba.py | cmp - dfba.py

outputs nothing, as expected. This is on Ubuntu 18.04.4 which has fgrep 3.1 (same as what you have).

I noticed that the file actual_output.txt that you attached had trailing CR at the end of each line, which would cause 'diff' to report a difference at any line. So perhaps the problem has to do with a Microsoft-oriented file system in your environment, or something like that.
