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> -</div> - -<div class="NAVFOOTER"> -<hr align="LEFT" width="100%" /> -<table summary="Footer navigation table" width="100%" border="0" cellpadding="0" -cellspacing="0"> -<tr> -<td width="33%" align="left" valign="top"><a href="process-control.html" -accesskey="P">Prev</a></td> -<td width="34%" align="center" valign="top"><a href="index.html" -accesskey="H">Home</a></td> -<td width="33%" align="right" valign="top"><a href="process-control-ps.html" -accesskey="N">Next</a></td> -</tr> - -<tr> -<td width="33%" align="left" valign="top">Process Control</td> -<td width="34%" align="center" valign="top"><a href="process-control.html" -accesskey="U">Up</a></td> -<td width="33%" align="right" valign="top"><tt class="COMMAND">ps</tt></td> -</tr> -</table> -</div> -</body> -</html> - |
