NAME

       comm - print lines common to two sorted files

SYNOPSIS

       comm [-123] file1 file2

OPTIONS

       -1     Suppress column 1 (lines present only in file1)

       -2     Suppress column 2 (lines present only in file2)

       -3     Suppress column 3 (lines present in both files)

EXAMPLES

       comm file1 file2    # Print all three columns

       comm -12 file1 file2
			   # Print only lines common to both files

DESCRIPTION

       Two  sorted files are read and compared.  A three column listing is produced.  Files only in file1 are in column 1; files only in file2 are
       in column 2; files common to both files are in column 3.  The file name - means stdin.

NAME

     comm -- select or reject lines common to two files

SYNOPSIS

     comm [-123f] file1 file2

DESCRIPTION

     The comm utility reads file1 and file2, which should be sorted lexically, and produces three text columns as output: lines only in file1;
     lines only in file2; and lines in both files.

     The filename ``-'' means the standard input.

     The following options are available:

     -1      Suppress printing of column 1.

     -2      Suppress printing of column 2.

     -3      Suppress printing of column 3.

     -f      Fold case in line comparisons.

     Each column will have a number of tab characters prepended to it equal to the number of lower numbered columns that are being printed.  For
     example, if column number two is being suppressed, lines printed in column number one will not have any tabs preceding them, and lines
     printed in column number three will have one.

     comm assumes that the files are lexically sorted; all characters participate in line comparisons.

EXIT STATUS

     comm exits 0 on success, >0 if an error occurred.

SEE ALSO

     cmp(1), diff(1), sort(1), uniq(1)

STANDARDS

     The comm utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
