Need to kill process 48 hours old

captnz · 09-29-2004, 10:14 PM

I need to get a script or learn how to make one that will tell me:

1. what emacs processes are running
2. kill the processes that are over 48 hours old.

in addition a little cron help would be nice. I want to have this process email me with what it killed when its done.

TIA

Try this at the command line:

Code:

ps -eo "%p %t %c" | grep emacs | grep "-" | grep -v " 1-"

If that successfully displays emacs sessions that have been running over two days, you should be able to do this:

Code:

#!/bin/bash
for x in `ps -eo "%p %t %c" | grep emacs | grep "-" | grep -v " 1-" | cut -c 1-5`; do
  echo Killing process: `ps -p $x -o "%p %a"`
  kill -9 $x
done

As root do

Code:

#top

You get a list of processes running on your machine.To kill one hit K,it asks you about PID(process' number).Enter a number,hit enter,then 9,enter.Process killed.Hit Q to leave.

Hi Cro,

I ran that with mine and get an output of:

132 9-03:45:15 emacs.

Can you explain what "9-03:45:15" means? Looks like 3 hours, 45 mins, and 15 seconds but what is the 9-? Thanks...

Nine days (plus three hours, forty-five minutes and 15 seconds)

(Gee - didn't know ps could do all that - you just made my day - thanks :-)

Groetjes,

Yeah, that was what I thought it was, but my server has a process with 42483-02:00:00 listed, and I haven't even had the server running that long, so I just had to check the ps source code to make sure... and it seems that's what it should be. My 42000 day process is some kind of anomaly
