But what happens when
you locate two files that seem to be identical? The best way to
tell the difference is with the cmp
(compare) command:
Command Format
cmp file1 file2
Example
In this example
the cmp command
is used to identify the first occurrence of a difference between
two files. The difference occurred at the 1638th character position
and was found on line 42.
$ cmp ~/.bashrc
~/user2/.bashrc
bshrc user2/bshrc
differ: char 1638, line 42
