<h4><a name="tag_04_123_01"></a>NAME</h4>
<blockquote>rmdir - remove directories</blockquote>
<h4><a name="tag_04_123_02"></a>SYNOPSIS</h4>
<blockquote class="synopsis">
<p><code><tt>rmdir</tt> <b>[</b><tt>-p</tt><b>]</b> <i>dir</i><tt>...</tt></code></p>
</blockquote>
<h4><a name="tag_04_123_03"></a>DESCRIPTION</h4>
<blockquote>
<p>The <i>rmdir</i> utility shall remove the directory entry specified by each <i>dir</i> operand.</p>
<p>For each <i>dir</i> operand, the <i>rmdir</i> utility shall perform actions equivalent to the <a href=
"../functions/rmdir.html"><i>rmdir</i>()</a> function called with the <i>dir</i> operand as its only argument.</p>
<p>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 <i>rmdir</i> utility, the application shall specify the subdirectory before the parent directory so that
the parent directory will be empty when the <i>rmdir</i> utility tries to remove it.</p>
</blockquote>
<h4><a name="tag_04_123_04"></a>OPTIONS</h4>
<blockquote>
<p>The <i>rmdir</i> utility shall conform to the Base Definitions volume of IEEE&nbsp;Std&nbsp;1003.1-2001, <a href=
"../basedefs/xbd_chap12.html#tag_12_02">Section 12.2, Utility Syntax Guidelines</a>.</p>
<p>The following option shall be supported:</p>
<dl compact>
<dt><b>-p</b></dt>
<dd>Remove all directories in a pathname. For each <i>dir</i> operand:
<ol>
<li>
<p>The directory entry it names shall be removed.</p>
</li>
<li>
<p>If the <i>dir</i> operand includes more than one pathname component, effects equivalent to the following command shall
occur:</p>
<pre>
<tt>rmdir -p $(dirname</tt> <i>dir</i><tt>)
</tt>
</pre>
</li>
</ol>
</dd>
</dl>

<h4><a name="tag_04_123_05"></a>OPERANDS</h4>

<p>The following environment variables shall affect the execution of <i>rmdir</i>:</p>
<dl compact>
<dt><i>LANG</i></dt>
<dd>Provide a default value for the internationalization variables that are unset or null. (See the Base Definitions volume of
IEEE&nbsp;Std&nbsp;1003.1-2001, <a href="../basedefs/xbd_chap08.html#tag_08_02">Section 8.2, Internationalization Variables</a> for
the precedence of internationalization variables used to determine the values of locale categories.)</dd>
<dt><i>LC_ALL</i></dt>
<dd>If set to a non-empty string value, override the values of all the other internationalization variables.</dd>
<dt><i>LC_CTYPE</i></dt>
<dd>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).</dd>
<dt><i>LC_MESSAGES</i></dt>
<dd>Determine the locale that should be used to affect the format and contents of diagnostic messages written to standard
error.</dd>

<hr>
<div class="box"><em>The following sections are informative.</em></div>
<h4><a name="tag_04_123_16"></a>APPLICATION USAGE</h4>
<blockquote>
<p>The definition of an empty directory is one that contains, at most, directory entries for dot and dot-dot.</p>
</blockquote>
<h4><a name="tag_04_123_17"></a>EXAMPLES</h4>
<blockquote>
<p>If a directory <b>a</b> in the current directory is empty except it contains a directory <b>b</b> and <b>a/b</b> is empty except
it contains a directory <b>c</b>:</p>
<pre>
<tt>rmdir -p a/b/c
</tt>
</pre>
<p>removes all three directories.</p>
</blockquote>
<h4><a name="tag_04_123_18"></a>RATIONALE</h4>
<blockquote>
<p>On historical System V systems, the <b>-p</b> 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 <i>dir</i> operand is not removed, but does not allow the status message reporting
success to be written as a diagnostic.</p>
<p>The <i>rmdir</i> utility on System V also included a <b>-s</b> option that suppressed the informational message output by the
<b>-p</b> option. This option has been omitted because the informational message is not specified by this volume of
IEEE&nbsp;Std&nbsp;1003.1-2001.</p>
</blockquote>
<h4><a name="tag_04_123_19"></a>FUTURE DIRECTIONS</h4>
<blockquote>
