Hey, I'm trying to figure out how to merge these two commands. The first one needs to be plugged into the second where it says <TTY>. I'm sure it's pretty simple, but I haven't yet found a way to do it. Thanks! -Jason

#Finds the current session of the given user <user>
<TTY> = w |grep <user> |grep 0.00s | cut -c 10-15

#Returns all the pids for all but the current session <TTY> of the given user <user>
ps uU <user> |grep pts/ |grep -v <TTY> | cut -c 10-14

Hey, I used the for expression to handle this problem, but apparently this command isn't formed correctly and I get > as a result.

$for tty in 'w |grep dsi |grep 0.00s | cut -c 10-15'; do for pid in 'ps uU dsi |grep pts/ |grep -v $tty | cut -c 10-14'; do kill $pid; done

To test it, I tried this command, with the following result:

$for tty in 'w |grep dsi |grep 0.00s | cut -c 10-15'; do echo $tty; done
w |grep dsi |grep 0.00s | cut -c 10-15

Not sure what I'm doing wrong. I would think I'd get some pids, since that's what I get when I run the following command:

w |grep dsi |grep 0.00s | cut -c 10-15

Any ideas?

Thanks,
Jason

So what is this telling you?

It is saying that tty only gets one value, that being the string 'w |grep dsi |grep 0.00s | cut -c 10-15', which it is then echoing.
Seems to have performed its task correctly.

I am guessing your question is why did it not return the values from your commands?
Answer: You have input a string and not a command substitution.

Have a look at MensaWater's solution and your answer lay there on how to correct it.

Thanks, MensaWater and grail. I should have reloaded the page before posting last Friday... Here's the final command that kills the PIDs:

ps uU <user> |grep pts/ |grep -v $(w |grep <user> |grep 0.00s | cut -c 10-15) | cut -c 10-14 | xargs kill

You should probably be a little cautious ... what happens when your username exceeds 10 characters? Your first cut will be in a bit of strife

In my case the usernames will always be 3 characters. Nothing to worry about. Thanks!
