These processes range from things -like the X Window System to system programs (daemons) that are started when the computer -boots. Every process runs as a particular user. Processes that are started at boot time -usually run as <tt class="USERNAME">root</tt> or <tt class="USERNAME">nobody</tt>. -Processes that you start will run as you. Processes started as other users will run as -those users.</p> - -<p>You have control over all the processes that you start. Additionally, <tt -class="USERNAME">root</tt> has control over all processes on the system, including those -started by other users. Processes can be controlled and monitored through several -programs, as well as some shell commands.</p> - -<div class="SECT1"> -<h1 class="SECT1"><a id="PROCESS-CONTROL-BACKGROUNDING" -name="PROCESS-CONTROL-BACKGROUNDING">11.1 Backgrounding</a></h1> - -<p>Programs started from the command line start up in the foreground. This allows you to -see all the output of the program and interact with it. However, there are several -occasions when you'd like the program to run without taking up your terminal. This is -called running the program in the background, and there are a few ways to do it.</p> - -<p>The first way to background a process is by adding an ampersand to the command line -when you start the program. For example, assume you wanted to use the command line mp3 -player <tt class="COMMAND">amp</tt> to play a directory full of mp3s, but you needed to -do something else on the same terminal. The following command line would start up amp in -the background:</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">%</samp> <kbd class="USERINPUT">amp *.mp3 &</kbd> -</pre> -</td> -</tr> -</table> - -<p>The program will run as normal, and you are returned to a prompt.</p> - -<p>The other way to background a process is to do so while it is running. First, start up -a program. While it is running, hit <b class="KEYCAP">Control</b>+<b -class="KEYCAP">z</b>. This suspends the process. A suspended process is basically paused. -It momentarily stops running, but can be started up again at any time. Once you have -suspended a process, you are returned to a prompt. You can background the process by -typing:</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">%</samp> <kbd class="USERINPUT">bg</kbd> -</pre> -</td> -</tr> -</table> - -<p>Now the suspended process is running in the background.</p> -</div> -</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="file-commands-link.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-foregrounding.html" -accesskey="N">Next</a></td> -</tr> - -<tr> -<td width="33%" align="left" valign="top">Aliasing files with <tt -class="COMMAND">ln</tt></td> -<td width="34%" align="center" valign="top"> </td> -<td width="33%" align="right" valign="top">Foregrounding</td> -</tr> -</table> -</div> -</body> -</html> - |
