CMSRF (COMPARE_SORTED_FILE) -- Find lines common to two files.
usage: CMSRF [-1] [-2] [-3] [-12] [-13] [-23] [-123]  file1 [file2]


FORMAT

  CMSRF [options] file1 [file2]


  CMSRF reads sorted files, file1 and file2, and produces 1-, 2-, or
  3-column output.  Column 1 contains lines found only in file1, column 2
  contains lines found only in file2, and column 3 contains lines found in
  both files. To compare unsorted files, use CMF (COMPARE_FILE).


ARGUMENTS

  Use of a hyphen for either file name will cause the data to be read from
  standard input.

  file1
  (required)       Specify first file for comparison.

  file2
  (optional)       Specify second file for comparison.
                   Default if omitted: compare file1 to standard input.

OPTIONS

  If no options are specified, CMSRF produces a complete 3-column report.

  -n               Specify number(s), where n is an integer sequence
                   representing the following:

                   1        Report only lines exclusive to file1.

                   2        Report only lines exclusive to file2.

                   3        Report only lines commmon to both files.

EXAMPLES

  1.  $ cmsrf -12 //us/sorted_stuff.c            Compare '//us/sorted_stuff.c
                                                  to standard input and report
                                                  lines found in either place,
                                                  but not both.

  2.  $ cmsrf -3 //us/sorted_stuff.a //us/sorted_stuff.b
                                                 Report only common lines
                                                  for both files.
