Wed Aug 26 10:00:38 CDT 2009 Slackware 13.0 x86_64 is released as stable! Thanks to everyone who helped make this release possible -- see the RELEASE_NOTES for the credits. The ISOs are off to the replicator. This time it will be a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD. We're taking pre-orders now at store.slackware.com. Please consider picking up a copy to help support the project. Once again, thanks to the entire Slackware community for all the help testing and fixing things and offering suggestions during this development cycle. As always, have fun and enjoy! -P.

+
+<p>If you need to interact with a backgrounded process, you can bring it back into the
+foreground. If you've only got one backgrounded process, you can bring it back by
+typing:</p>
+
+<table border="0" bgcolor="#E0E0E0" width="100%">
+<tr>
+<td>
+<pre class="SCREEN">
+<samp class="PROMPT">%</samp> <kbd class="USERINPUT">fg</kbd>
+</pre>
+</td>
+</tr>
+</table>
+
+<p>If the program is not done running, the program will take control over you terminal
+and you will not be returned to a prompt. Sometimes, the program will finish running
+while backgrounded. In this instance, you'll get a message like this:</p>
+
+<table border="0" bgcolor="#E0E0E0" width="100%">
+<tr>
+<td>
+<pre class="SCREEN">
+[1]+ Done /bin/ls $LS_OPTIONS
+</pre>
+</td>
+</tr>
+</table>
+
+<p>That tells you that the backgrounded process (in this case <tt class="COMMAND">ls</tt>
+- not terribly interesting) has completed.</p>
+
+<p>It is possible to have several processes backgrounded at once. When this happens,
+you'll need to know which process you want to bring back to the foreground. Just typing
+<tt class="COMMAND">fg</tt> will foreground the process that was last backgrounded. What
+if you had a whole list of processes in the background? Luckily, bash includes a command
+to list all the processes. It's called <tt class="COMMAND">jobs</tt> and gives output
+like so:</p>
+
+<table border="0" bgcolor="#E0E0E0" width="100%">
+<tr>
+<td>
+<pre class="SCREEN">
+<samp class="PROMPT">%</samp> <kbd class="USERINPUT">jobs</kbd>
+[1] Stopped vim
+[2]- Stopped amp
+[3]+ Stopped man ps
+</pre>
+</td>
+</tr>
+</table>
+
+<p>This shows you a list of all the processes that are backgrounded. As you can see, they
+are all stopped. This means that the processes are suspended. The number is a sort of ID
+for all the backgrounded processes. The ID with a plus sign beside it (<var
+class="LITERAL">man ps</var>) is the process that will be foregrounded if you just type
+<tt class="COMMAND">fg</tt>.</p>
+
+<p>If you wanted to foreground <tt class="COMMAND">vim</tt>, you would type:</p>
+
+<table border="0" bgcolor="#E0E0E0" width="100%">
+<tr>
+<td>
+<pre class="SCREEN">
+<samp class="PROMPT">%</samp> <kbd class="USERINPUT">fg 1</kbd>
+</pre>
+</td>
+</tr>
+</table>
+
+<p>and <tt class="COMMAND">vim</tt> would spring back up to the console. Backgrounding
+processes can be very useful if you only have one terminal open over a dialup connection.
+You can have several programs running on that one terminal, periodically switching back
+and forth between them.</p>
