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>

<p>There are several options for <tt class="COMMAND">touch</tt>, including options to

<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

<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
