COMM(1)COMM(1)NAMEcomm - select or reject lines common to two sorted files
SYNOPSIScomm [ - [ 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.
