rmdir - remove directories
Návod, kniha: POSIX Programmer's Manual
rmdir [-p] dir...
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.
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:
The following operand shall be supported:
- dir
- A pathname of an empty directory to be removed.
Not used.
None.
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 .
Default.
Not used.
The standard error shall be used only for diagnostic messages.
None.
None.
The following exit values shall be returned:
- 0
- Each directory entry specified by a dir operand was
removed successfully.
- >0
- An error occurred.
Default.
The following sections are informative.
The definition of an empty directory is one that contains, at most, directory
entries for dot and dot-dot.
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:
removes all three directories.
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.
None.
