ummm this is a bit tricky, for the user may be running a valid job in
batch or through nohup. You wouldnt want to kill that. But it often
happened in our cc lab that users wouldnt log out properly simply hit
<CTRL><ALT><BKSPC> and leave the terminal, leaving their window managers
hogging a substantial amount of resources.
One could run a process in the background which does a "ps aux" and for
each unique user ( have to take care of root and other daemon owners, uid
value should be a better test) find whether he/she is logged in (grep who).
Once we detect a process owned by an user not currently logged in, check
the "nice" value ( I guess nohup changes this ), if thats a legal
background priority keep it otherwise kill it.
Bash script with a bit of awk should do it. As for myself ( still to
know awk) i will have to use c
sreangsu
