<strong>Synopsis</strong>
|
|
|
|
<p><strong>dirname</strong> <em>string</em></p>
|
|
|
|
<p><strong>Description</strong></p>
|
|
|
|
<p>You can use <strong>dirname</strong> to delete the filename
|
|
portion, beginning with the last slash character (/) to the end of
|
|
<em>string</em>, and write the result to standard output. The <em>
|
|
string</em> is processed using the following rules:</p>
|
|
|
|
<ul>
|
|
<li>If <em>string</em> consists entirely of slash characters, a
|
|
single slash character is written to standard output and processing
|
|
ends.</li>
|
|
|
|
<li>If there are any trailing slash characters in <em>string</em>,
|
|
they are removed.</li>
|
|
|
|
<li>If there are no slash characters remaining in <em>string</em>,
|
|
a period character is written to standard output and processing
|
|
ends.</li>
|
|
|
|
<li>If there are trailing non-slash characters in <em>string</em>,
|
|
they are removed.</li>
|
|
|
|
<li>If there are any trailing slash characters in <em>string</em>,
|
|
they are removed.</li>
|
|
|
|
<li>If the remaining string is empty, <em>string</em> is set to a
|
|
single slash character.</li>
|
|
</ul>
|
|
|
|
<p><strong>Operands</strong></p>
|
|
|
|
<p>The <em>string</em> operand is the pathname of which <strong>
|
|
dirname</strong> will return the directory portion of.</p>
|
|
|
|
<p><strong>Exit Status</strong></p>
|
|
|
|
<ul>
|
|
<li>0 on success</li>
|
|
|
|
<li>>0 if an error occurs.</li>
|
|
</ul>
