Slackware 13.37slackware-13.37
Mon Apr 25 13:37:00 UTC 2011 Slackware 13.37 x86_64 stable is released! Thanks to everyone who pitched in on this release: the Slackware team, the folks producing upstream code, and linuxquestions.org for providing a great forum for collaboration and testing. The ISOs are off to be replicated, a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD. Please consider supporting the Slackware project by picking up a copy from store.slackware.com. We're taking pre-orders now, and offer a discount if you sign up for a subscription. As always, thanks to the Slackware community for testing, suggestions, and feedback. :-) Have fun!

+
+<p><tt class="COMMAND">touch</tt>(1) is used to change the timestamp on a file. You can
+change access timestamps and modification timestamps with this command. If the file
+specified does not exist, <tt class="COMMAND">touch</tt> will create a zero length file
+with the name specified. To mark a file with the current system time, you would issue
+this command:</p>

+<table border="0" bgcolor="#E0E0E0" width="100%">

+
+<p>There are several options for <tt class="COMMAND">touch</tt>, including options to
+specify which timestamp to modify, the time to use, and many more. The online manual page
+discusses these in detail.</p>

+<h2 class="SECT2"><a id="AEN3639" name="AEN3639">10.4.2 <tt
+class="COMMAND">mkdir</tt></a></h2>
+
+<p><tt class="COMMAND">mkdir</tt>(1) will create a new directory. You simply specify the
+directory to create when you run mkdir. This example creates the <tt
+class="FILENAME">hejaz</tt> directory in the current directory:</p>

+<p>You can also specify a path, like this:</p>
+
+<table border="0" bgcolor="#E0E0E0" width="100%">
+<tr>
+<td>
+<pre class="SCREEN">
+<samp class="PROMPT">%</samp> <kbd class="USERINPUT">mkdir /usr/local/hejaz</kbd>
+</pre>
+</td>
+</tr>
+</table>
+
+<p>The <var class="OPTION">-p</var> option will tell <tt class="COMMAND">mkdir</tt> to
+make any parent directories. The above example will fail if <tt
+class="COMMAND">/usr/local</tt> does not exist. The <var class="OPTION">-p</var> option
+will create <tt class="FILENAME">/usr/local</tt> and <tt
+class="FILENAME">/usr/local/hejaz</tt>:</p>
