I looked here help.ubuntu.com (and on the german ubuntu-user wiki) but couldnt find an answer.
I dont know what they mean e.g. in the manpage of mpstat
:
SYNOPSIS
mpstat [ -A ] [ -u ] [ -V ] [ -I { keyword [,...] | ALL } ] [ -P { cpu [,...] | ON | ALL } ] [ interval [ count ] ]
when they say -I { keyword [,...] | ALL }
or -P { cpu [,...] | ON | ALL }
I would appreciate any clarification.
