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"
Changelog:
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
