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