dircmp(1)




NAME

     dircmp - directory comparison


SYNOPSIS

     dircmp [-ds] [-w n] dir1 dir2


DESCRIPTION

     The dircmp command examines  dir1  and  dir2  and  generates
     various  tabulated  information  about  the  contents of the
     directories. Listings of  files  that  are  unique  to  each
     directory are generated for all the options. If no option is
     entered, a list is output indicating whether the file  names
     common to both directories have the same contents.


OPTIONS

     The following options are supported:

     - d   Compares the contents of files with the same  name  in
           both  directories  and output a list telling what must
           be changed in the two files to bring them into  agree-
           ment. The list format is described in diff(1).

     -s    Suppresses messages about identical files.

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

      dir1
