Linux implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior),
or the interface may not be implemented on Linux.
Имя (Name)
rmdir — remove directories
Синопсис (Synopsis)
rmdir [-p] dir...
Описание (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.
Параметры (Options)
The rmdir utility shall conform to the Base Definitions volume of
POSIX.1‐2017, 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)
Операнды (Operands)
The following operand shall be supported:
dir A pathname of an empty directory to be removed.
Стандартный ввод (Stdin)
Not used.
Входные файлы (Input files)
None.
Переменные окружения (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 POSIX.1‐2017, 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.
Асинхронные события (Asynchronous events)
Default.
Стандартный вывод (Stdout)
Not used.
Стандартный вывод сообщений (Stderr)
The standard error shall be used only for diagnostic messages.
Выходные файлы (Output files)
None.
Расширенное описание (Extended description)
None.
Статус выхода (Exit)
The following exit values shall be returned:
0 Each directory entry specified by a dir operand was removed
successfully.
>0 An error occurred.
Последствия ошибок (Consequences of errors)
Default.
The following sections are informative.
Использование в приложениях (Application usage)
The definition of an empty directory is one that contains, at
most, directory entries for dot and dot-dot.
Примеры (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.
Обоснование (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 POSIX.1‐2017.
Будущие направления (Future directions)
None.
