LinuxQuestions.org - Find process information by name.

Is there a way to find out information about a process based on the command used to run it?

Ideally I would like to get processes ID %CPU and memory usage back.
I have written a short shell script which does this but I wonderd was there a command that did this.

Here's my shell script

Code:

#!/bin/bash



ExpectedArgs=1

ARGS=$#



if [ $ARGS != $ExpectedArgs ]

then

        echo "Incorrect number of arguments"

        echo "Usage: PSscript <process name>"

else

        ps -eo pid,comm,pcpu,pmem,rsz,vsz | awk -v proc=$1 \

                'NR == 1 {print} \

                {if ($2 == proc) {print}} \

                '

fi

I would also like any feedback if possible on ways to make my code better (better input validation or better code layout etc.)

Thanks in advance :)
