NAME
     dircmp - directory comparison

SYNOPSIS
     dircmp [-d] [-s] [-w n] [--] dir1 dir2

DESCRIPTION
     dircmp compares two directories dir1 and dir2 and tells you whether
     they contain files of the same name and whether such files also have
     the same contents.

OPTIONS
     No option specified:
          dircmp first lists the file names that are unique to each direc-
          tory. Files from dir1 are shown on the left, while files from
          dir2 appear on the right. The output is generated in the follow-
          ing format:

          Nov  16  10:42  1987  dir1 only dir2 only Page 1

          ./filename1              ./filename2
                .                         .
                .                         .
                .                         .
                .                         .

          The next set of lines provides information as to whether files
          common to the two directories have the same contents. If this is
          the case, they are listed in a line that begins with same; if
          not, in a line that begins with different. The generated output
          is in the following format:

          directory .
          different ./filename in dir1 and dir2
                .
                .
                .
          same      ./filename in dir1 and dir2

     -d   dircmp compares the contents of identically named files in dir1
          and dir2 and outputs the results in a diff-like format. The
          result of this comparison is output immediately after the file
          name comparison.

     -s   dircmp suppresses information about the contents of common files.

     -w n The width of the output line is changed to n characters. The
          default width is 72 characters per line.

     --   If dir1 begins with a dash (-), the end of the command-line
          options must be marked with --.

     dir1 dir2
          Names of the directories you wish to compare.

LOCALE
     The LCMESSAGES environment variable governs the language in which
     message texts are displayed. If LCMESSAGES is undefined or is defined
     as the null string, it defaults to the value of LANG. If LANG is like-
     wise undefined or null, the system acts as if it were not internation-
     alized.

     The LCALL environment variable governs the entire locale. LCALL
     takes precedence over all the other environment variables which affect
     internationalization.

EXAMPLES
     Comparison of the two directories A and B, which have the following
     contents:

     _________________________________________
    | Directory | File names | File contents |
    ||||
    | A         | a          | aaaaaaa       |
    |           |____________|_______________|
    |           | b          | bbbb          |
    |           |____________|_______________|
    |           | c          | cccc          |
    |           |____________|_______________|
    |           | d          | dddd          |
    |___________|____________|_______________|
    | B         | a          | aaaaaaaaa     |
    |           |____________|_______________|
    |           | b          | BBBB          |
    |           |____________|_______________|
    |           | C          | cccc          |
    |           |____________|_______________|
    |           | d          | dddd          |
    |___________|____________|_______________|
