Linux – List linux processes having windows

linuxpsxorg

How can I list linux processes (like ps aux) but only those having X11 windows?

I guess there must be some simple connection (like always in linux) between the processes and the X server. Is it exposed to lsof ?

xwininfo -tree -root | grep -v "has no name" | grep -v child

It's a bit of a different approach than what you requested: instead of listing processes, it lists windows. If you're looking for a list of process ID numbers, this doesn't accomplish the task. If you're looking for a list of what's running, this does.

Obviously, this approach will not show you the name of any program that has "child" as part of its name. Still, if you're looking for a quick and easy option that will serve most purposes, this may be one.

Oh, and by the way, there are a number of other options to "xwininfo", such as being able to specify the name of just one window (instead of specifying the "root" window).

Linux – kill all processes of a user except a few in linux

Kinda hackerish:

ps -U tim | egrep -v "ssh|screen" | cut -b11-15 | xargs -t kill

this will kill everything but any ssh or screen processes. Here are the commands explained:

ps -U tim -- will obviously, list every process from the user tim
egrep -v "ssh|screen" -- will remove lines with ssh or screen processes
cut -b11-15 -- will cut the data in columns 11-15 (typically that's where the PID is located
xargs -t kill -- will pass all the process ID's to the kill command

You can also use awk, if you're more used to that.

ps -U tim | egrep -v "ssh|screen" | awk '{print $2}' | xargs -t kill

ps -aef to get a more comprehensive list.

ps axwww also works fine.
