Answer 2

Answer:  

The command “cmp” is used to compare two files “byte by byte”.

Explanation:

When we compare two files, if there is any difference found in the file, that command reports the location, where the first mismatch is found in the file. If there is no difference found in the file and it is identical.

It does not bother about the continuous mismatch, but it displays the first mismatch.
