COMM(1)                 GENIX Programmer's Manual                 COMM(1)



      NAME
           comm - select or reject lines common to two sorted files

      SYNOPSIS
           comm [ - [ 123 ] ] file1 file2

      DESCRIPTION
           Comm reads file1 and file2, which should be ordered in ASCII collat-
           ing  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.
