dircmp(1)

NAME

dircmp — directory comparison

SYNOPSIS

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

DESCRIPTION

dircmp 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.

-d: 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).
-s: Suppress messages about identical files.
-wn: Change the width of the output line to n characters. The default width is 72.

EXTERNAL INFLUENCES

Environment Variables

LC_COLLATE determines the order in which the output is sorted.

If LC_COLLATE is not specified in the environment or is set to the empty string, the value of LANG is used as a default. If LANG is not specified or is set to the empty string, a default of ``C'' (see lang(5)) is used instead of LANG. If any internationalization variable contains an invalid setting, dircmp 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

Compare the two directories slate and sleet and produce a list of changes that would make the directories identical:

dircmp -d slate sleet 

WARNINGS

This command is likely to be withdrawn from X/Open standards. Applications using this command might not be portable to other vendors' systems. As an alternative diff -R is recommended.
