NAME

6       comm - select or reject lines common to two sorted files
7

SYNOPSIS

9       comm [ - [ 123 ] ] file1 file2
10

DESCRIPTION

12       Comm  reads file1 and file2, which should be ordered in ASCII collating
13       sequence, and produces a three column  output:  lines  only  in  file1;
14       lines  only  in file2; and lines in both files.  The filename `-' means
15       the standard input.
16
17       Flags 1, 2, or 3 suppress printing of the corresponding  column.   Thus
18       comm -12 prints only the lines common to the two files; comm -23 prints
19       only lines in the first file but not in the second; comm -123 is a  no-
20       op.
