-<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>
