Killall!!!!!

Have you ever been frustrated when there are millions of unwanted processes running in a server and you need to kill them all?
And to make matters worse "killall" just doesn't seem to work!!!

I made this little script to solve this issue , you can kill any process with a given string in its name or any processes from a given user


#!/bin/bash

if [ "$1" == "-u" ] ; then
        PID=`cat /etc/passwd | grep "$2" | cut -d ":" -f3`
        processes=`ps aux | grep "$PID" | egrep -v "PID|ps \-au|killbyname|grep" | awk '{ print $2}'`
        echo "############# Killing all processes of user: $2 ############################"
else
        echo "############# Killing processes by name: $1 ############################"
        processes=`ps aux | grep "$1" | egrep -v "killbyname|grep" | awk '{ print $2}' `
fi


for process in $processes ; do
        command=`ps aux | grep $process | egrep -v "grep" | awk '{ print $2 }'`
        echo "Killing process: $process"
        echo ""
        kill -9 $process
done

USAGE:

./killbyname.sh "name"

Will kill any process with "name" in its running path , important to remember that if the process has "name" in any part of its running path it will be killed.

./killbyname.sh -u "username"

Will kill any processes being run by the specified username.

Feel free to improve it!
