Linux - Find the pid of a running script, Return PID using ps and awk

Find the pid of a running script

Today when I was running my firefox, I ran into an issue and I thought to find the PID of the firefox and the command it was using. I'm sure it's totally overkill and there is a much easier way I didn't find to do this, but after some scouring of The Google, I found something that works!

# ps -ef | grep firefox
  malu   2311     1  1 18:44 ?        00:00:14 /usr/lib/firefox-3.6/firefox
  malu    2671  2570  0 18:59 pts/0    00:00:00 grep --color=auto firefox

A little bit more data than I wanted, So by adding other commands I found the result.

# ps -eo pid,command | grep "firefox" 
  2311 /usr/lib/firefox-3.6/firefox
  2909 grep --color=auto firefox

Remove the unwanted line

# ps -eo pid,command | grep "firefox" | grep -v 'grep'
  2311 /usr/lib/firefox-3.6/firefox

Find only yhe PID of the script.

# ps -eo pid,command | grep "firefox" | grep -v grep | awk '{print $1}'
  2311
