NAME
dircmp - directory comparison (LEGACY)
SYNOPSIS
dircmp [-ds] dir1 dir2
DESCRIPTION
The
dircmp
utility
examines the directory hierarchies specified by
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 specified,
a list is output that indicates whether the
filenames common to both directories
have the same contents.
OPTIONS
The
dircmp
utility supports the XBD specification, Utility Syntax Guidelines .
The following options are supported:
- -d
- Compare the contents of files with the same name in
both directories and output a list indicating what must
be changed in the two files to bring them into agreement.
The list format is described in
diff.
- -s
- Suppress messages about identical files.
OPERANDS
The following operands are supported:
- dir1
-
- dir2
- A pathname of a directory to be compared.
STDIN
Not used.
INPUT FILES
None.
ENVIRONMENT VARIABLES
The following environment variables may affect the execution of
dircmp:
- LANG
- Provide a default value for the internationalisation variables
that are unset or null.
If
LANG
is unset or null, the corresponding value from the
implementation-dependent default locale will be used.
If any of the internationalisation variables contains an invalid setting, the
utility will behave as if none of the variables had been defined.
- LC_ALL
-
If set to a non-empty string value,
override the values of all the other internationalisation variables.
- LC_COLLATE
-
Determine the locale for the ordering of the output.
- LC_CTYPE
-
Determine the
locale for the interpretation of sequences of bytes of text data as
characters (for example, single- as opposed to multi-byte characters
in arguments and input files).
- LC_MESSAGES
-
Determine the locale that should be used to affect
the format and contents of diagnostic
messages written to standard error.
- NLSPATH
-
Determine the location of message catalogues
for the processing of
LC_MESSAGES .
ASYNCHRONOUS EVENTS
Default.
STDOUT
The output format of
dircmp
is unspecified, but includes:
-
lists of pathnames in either
dir1
or
dir2,
but not both
-
when
-d
is given, listings of differences between files, as produced by
diff.
STDERR
Used only for diagnostic messages.
OUTPUT FILES
None.
EXTENDED DESCRIPTION
None.
EXIT STATUS
The following exit values are returned:
- 0
- Successful completion.
- >0
- An error occurred.
(Differences in directory contents are not considered errors.)
CONSEQUENCES OF ERRORS
