NAME

SYNOPSIS

       comm [OPTION]... FILE1 FILE2

DESCRIPTION

       Compare sorted files FILE1 and FILE2 line by line.

       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.

       -1     suppress column 1 (lines unique to FILE1)

       -2     suppress column 2 (lines unique to FILE2)

       -3     suppress column 3 (lines that appear in both files)

       --check-order
	      check that the input is correctly sorted, even if all input lines are pairable

       --nocheck-order
	      do not check that the input is correctly sorted

       --output-delimiter=STR
	      separate columns with STR

       --help display this help and exit

       --version
	      output version information and exit

       Note, comparisons honor the rules specified by `LC_COLLATE'.

EXAMPLES

       comm -12 file1 file2

       comm -3
	      file1 file2  Print lines in file1 not in file2, and vice versa.
