COMM(1L)          MISC. REFERENCE MANUAL PAGES           COMM(1L)



NAME
     comm - compare two sorted files line by line

SYNOPSIS
     comm [-123] file1 file2

DESCRIPTION
     This manual page documents the GNU version  of  comm.   comm
     prints  lines that are common, and lines that are unique, to
     two input files.  The two files must be sorted  before  comm
     can be used.  The file name `-' means the standard input.

     With no options, comm produces three column output.   Column
     one  contains  lines  unique  to  _f_i_l_e_1, column two contains
     lines unique to _f_i_l_e_2, and column three contains lines  com-
     mon to both files.

  OPTIONS
     The  options  -_1,  -_2,  and  -_3  suppress  printing  of  the
     corresponding columns.
