+.th COMM I 8/21/73
+.sh NAME
+comm \*- print lines common to two files
+.sh SYNOPSIS
+.bd comm
+[
+.bd \*-
+[
+.bd 123
+]
+] file1 file2
+[
+file3
+]
+.sh DESCRIPTION
+.it Comm
+reads
+.it file1
+and
+.it file2,
+which should be in sort,
+and produces a three column output: lines only in
+.it file1;
+lines only in
+.it file2;
+and lines in both files.
+.s3
+If
+.it file3
+is given, the output will be placed there;
+otherwise it will be written on the standard output.
+.s3
+Flags 1, 2, or 3 suppress printing of the corresponding
+column.
+Thus
+.bd comm
+.bd \*-12
+prints only the lines common to the two files;
+.bd comm
+.bd \*-23
+prints only lines in the first file but not in the second;
+.bd comm
+.bd \*-123
+is a no-op.
