Depends on cpulimit, the original software appears to be a dead project but a fork exists.
#!/usr/bin/python # -*- coding: utf-8 -*- """ #------------------------------------------------------------------------------- processes.py - version 7 by Vlad George #------------------------------------------------------------------------------- Description: This script pipes a process manipulation menu into the openbox menu. Usage: Just place this script in ~/.config/openbox/scripts, make it executable; if you want you can enlist the processes which should not be shown in the unwanted_procs list below, then add following to your ~/.config/openbox/menu.xml: "<menu id="proc-menu" label="processes" execute="~/.config/openbox/scripts/processes.py" />... <menu id="root-menu" label="Openbox3">...<menu id="proc-menu" />...</menu>" and reconfigure openbox. To enable cpu usage display uncomment the lines marked with (***) (lines 106-108 and 146). Note: You need 'ps'. To enable cpulimit just uncomment the lines marked with (#*#) (lines 158-169). Note: You need 'cpulimit'. Get it from here: "http://cpulimit.sourceforge.net" Spoiledbroth: Here is an updated fork of cpulimit https://github.com/torden/cpulimit Changelog: 28.02.18: 7th version - Openbox wiki editor added a link to an updated fork of cpulimit (untested with script) 20.02.07: 7th version - added "-z" flag to cpulimit; added ValueError handling for printXml; added --title flag 04.12.07: 6th version - added cpulimit; to enable it just uncomment the lines marked with (#*#) 18.11.07: 5th version - processes alphabetically sorted 22.10.07: 4th version - totally removed SleepAVG from script. for kernels < 2.6.20 please use earlier versions. simplified cpu usage command. 07.07.07: 3rd version - added cpu usage; since SleepAVG was removed from /proc (2.6.20), it will be only displayed depending on running kernel version 17.02.07: 2nd version - shortened procData #------------------------------------------------------------------------------- This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
