I need to be able to turn the greped output of 'ps -e' into a list of PID's.

ie.

2073 ? 00:00:00:00 xmms
2074 ? 00:00:00:00 xmms
2075 ? 00:00:00:00 xmms
2076 ? 00:00:00:00 xmms

into

2073 2074 2075 2076



I've read the man and info pages of sed several times as well as the tutorial on the rute pages but I can't work out how to do it!


The only thing I've manages to do is get sed to recognise the actual PID's using /([0-9][0-9][0-9][0-9]/) however I can't do the rest.

Can any sed expert give me a hand?

Cheers

Why do you need all the pid's in one line ?

I suggest you use awk in the following manner

ps -e | grep xmms | awk '{print $1}'

Hope this helps.

In a line so I can create a varyable that can be placed after a kill command to kill the apps.


I'm making a script that will automaticaly kill and restart any program if it stops responding.


I'll try your suggestion then get back to you.

pkill xmms

Or you could go the old way:
kill `ps -ef | grep xmms | awk '{print $2}'`

The awk thing works perfectly.

I need the PID's in a var for other reasons too so the pkill thing, although good, isn't what I'm looking for.
