pgrep on AIX

Posted on by bunditj

It has been annoying from time to time when I switch to support non-linux platform, especially and mostly on AIX. I love to use pgrep to shorten a ps command to find out PID (process ID), that has never existed on AIX.

This script is very simple to use of pgrep and placed on /usr/local/bin or wherever you set an environment variable PATH.

# pgrep alike

while [ $# -gt 0 ]
 do
 #echo "$1"
 if [[ "$1" != "-"* ]]; then
 break;
 fi
 shift
 done

ps -o pid,args -e|grep "$1" |grep -v grep

Here is the output example from my AIX platform

[oracle@host01 ~]$ pgrep -lf pmon
 9699392 asm_pmon_+ASM
14680280 ora_pmon_cdb
18088032 ora_pmon_emrep

In summary, this script will ignore an option starting with – (minus), and use another as pattern searching on grep command.
