You might encounter situations where you need to kill group of processes, such as when google-chrome is running. Chrome spawns multiple processes and you might want to shut it down from terminal.
[rozaydin@RO ~]$ ps -e | grep chrome
5017 ? 00:00:01 chrome
5027 ? 00:00:00 chrome-sandbox
5028 ? 00:00:00 chrome
5033 ? 00:00:00 chrome-sandbox
5036 ? 00:00:00 chrome
5055 ? 00:00:00 chrome
5083 ? 00:00:00 chrome
5091 ? 00:00:00 chrome
5107 ? 00:00:00 chrome
5111 ? 00:00:00 chrome
5115 ? 00:00:00 chrome
5123 ? 00:00:00 chrome
5131 ? 00:00:00 chrome
5139 ? 00:00:00 chrome
5142 ? 00:00:00 chrome
5154 ? 00:00:00 chrome
5160 ? 00:00:00 chrome
[rozaydin@RO ~]$
Killing these processes one by one is a tedious task instead you can use below command the kill them with one single line. (
Bird massacre with single stone)
ps -e | grep <processname> | awk '{system("kill -9 "$1)}'
[rozaydin@RO ~]$ ps -e | grep chrome | awk '{system("kill -9 "$1)}'
sh: line 0: kill: (5033) - No such process
