dircmp(1) dircmp(1)

NAME

dircmp - directory comparison

SYNOPSIS

dircmp [-d][-s][

-wn ] 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 direc-

tories 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This command is likely to be withdrawn from X/Open standards.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.
