dircmp(1) General Commands Manual dircmp(1)
NAME
dircmp - directory comparison
SYNOPSIS
n] dir1 dir2
DESCRIPTION
examines dir1 and dir2 and generates various tabulated information about the contents of the directories. Sorted listings of files that
are unique to each directory are generated for all the options. If no option is entered, a sorted list is output indicating whether the
filenames common to both directories have the same contents.
Compare 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 agreement. The list
format is described in diff(1).
Suppress messages about identical files.
Change the width of the output line to
n characters. The default width is 72.
EXTERNAL INFLUENCES

behaves as if all internationalization variables are set to ``C'' (see environ(5)).
International Code Set Support
Single- and multi-byte character code sets are supported.
EXAMPLES
