seeing running processes

albean · 11-11-2002, 11:45 AM

My basic question is "How do you find out what processes are running on your linux box?"

I've learned about "ps" but I've run into a few problems and can't turn up anything on google.

1) Is there anything else besides "ps"
2) When I use a Shell window in KDE to run ps I don't see more than three processes but I know that there has to be others running.
3) When I execute a program I would like to see what processes it spawns is there an easy way to trace what process(es) a certain executable creates when it is run?

thanks,
Al

You can always use apropos to find out more information about a specific topic (if it's part of a manpage), e. g.

Quote:

apropos processes
fuser (1) - identify processes using files or sockets
killall (1) - kill processes by name
perlipc (1) - Perl interprocess communication (signals, fifos, pipes, safe subprocesses, sockets, and semaphores)
pgrep (1) - look up or signal processes based on name and other attributes
pkill [pgrep] (1) - look up or signal processes based on name and other attributes
pstree (1) - display a tree of processes
renice (8) - alter priority of running processes
top (1) - display top CPU processes

top is another program to show resources used.

Cool

Thanks guys, top did the trick and I'm sure I will be using apropos.

Thanks!
