RMDIR
Section: POSIX Programmer's Manual (P)
Updated: 2003
NAME
rmdir - remove directories
SYNOPSIS
rmdir [-p] dir...
DESCRIPTION
The rmdir utility shall remove the directory entry specified
by each dir operand.
For each dir operand, the rmdir utility shall perform
actions equivalent to the rmdir() function called with the dir
operand as its only argument.
Directories shall be processed in the order specified. If a directory
and a subdirectory of that directory are specified in a
single invocation of the rmdir utility, the application shall
specify the subdirectory before the parent directory so that
the parent directory will be empty when the rmdir utility tries
to remove it.
OPTIONS
The rmdir utility shall conform to the Base Definitions volume
of IEEE Std 1003.1-2001, Section 12.2, Utility Syntax Guidelines.
The following option shall be supported:
- -p
-
Remove all directories in a pathname. For each dir operand:
-
- 1.
-
The directory entry it names shall be removed.
- 2.
-
If the dir operand includes more than one pathname component,
effects equivalent to the following command shall
occur:
-
rmdir -p $(dirname dir)
OPERANDS
The following operand shall be supported:
- dir
-
A pathname of an empty directory to be removed.
STDIN
Not used.
INPUT FILES
None.
ENVIRONMENT VARIABLES
The following environment variables shall affect the execution of
rmdir:
- LANG
-
Provide a default value for the internationalization variables that
are unset or null. (See the Base Definitions volume of
IEEE Std 1003.1-2001, Section 8.2, Internationalization Variables
for
the precedence of internationalization variables used to determine
the values of locale categories.)
- LC_ALL
-
If set to a non-empty string value, override the values of all the
other internationalization variables.
- LC_CTYPE
-
Determine the locale for the interpretation of sequences of bytes
of text data as characters (for example, single-byte as
opposed to multi-byte characters in arguments).
- 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 catalogs for the processing of LC_MESSAGES
.
ASYNCHRONOUS EVENTS
Default.
STDOUT
Not used.
STDERR
The standard error shall be used only for diagnostic messages.
OUTPUT FILES
None.
EXTENDED DESCRIPTION
None.
EXIT STATUS
The following exit values shall be returned:
- 0
-
Each directory entry specified by a dir operand was removed
successfully.
- >0
-
An error occurred.
CONSEQUENCES OF ERRORS
Default.
The following sections are informative.
APPLICATION USAGE
The definition of an empty directory is one that contains, at most,
directory entries for dot and dot-dot.
EXAMPLES
If a directory a in the current directory is empty except it
contains a directory b and a/b is empty except
it contains a directory c:
-
rmdir -p a/b/c
removes all three directories.
RATIONALE
On historical System V systems, the -p option also caused a
message to be written to the standard output. The message
indicated whether the whole path was removed or whether part of the
path remained for some reason. The STDERR section requires this
diagnostic when the entire path specified by a dir operand is
not removed, but does not allow the status message reporting
success to be written as a diagnostic.
The rmdir utility on System V also included a -s option
that suppressed the informational message output by the
-p option. This option has been omitted because the informational
message is not specified by this volume of
IEEE Std 1003.1-2001.
FUTURE DIRECTIONS
None.
