comm - compare two sorted files line by line
comm [OPTION]... FILE1 FILE2
Compare sorted files FILE1 and FILE2 line by line.
When FILE1 or FILE2 (not both) is -, read standard input.
With no options, produce three-column output. Column one contains lines unique to FILE1, column two contains lines unique to FILE2, and column three contains lines common to both files.
Note, comparisons honor the rules specified by 'LC_COLLATE'.
