== Killing a program ==
The ‘kill’ command is used to forcefully end a process that is not responding. Technicians can kill the inactivity or session timer(s) when working on a particular workstation and don’t want to be bothered with timers or pop-ups.

To kill a program you must first find the process ID (PID); type the following command to receive a list of processes and their PIDs <font class="code">ps aux</font>. The first column is the user running the process, the second column is the PID. To kill a particular process type <font class="code">kill [pid]</font>, if the process refuses, type <font class="code">kill -9 [pid]</font> for a more forceful attempt. 

If you know the name of the application you want to kill, you can add the grep command followed by the program name to only display that program. For example, to search for the PID for Firefox, type <font class="code">ps aux | grep firefox</font>; this will display results for any application named firefox.

To kill just the inactivity timer, type <font class="code">kill xautolock</font>, type <font class="code">kill pacrez</font> to kill the session timer.

==== Killing a program in the Groovix GUI ====
If you can’t find the PID or have the process you want to kill open in the desktop, open a new xterm window and type <font class="code">xkill</font>; this will change the mouse cursor to an X and will kill the first process window you click on with your mouse.
