ps List running processes
 
This is a small 'ps' replacement, which uses information
available via sysctl(3) interface. It's primitive, but
gives you the most important informations, i.e. how many
processes are running and on which vty, and the pid number
to kill some of them. :-)
 
Currently, no options are implemented yet.
