Kill process by name using Bash? [duplicate]

Question

I've got many java processes running with different jar files. I want to kill on explicit jar file process.

the following command doesn't work successfully:

sudo kill $(ps -ef | grep example.jar | awk '{print $2}')

It finds the correct PID, but can't kill it.

Answer 1

Try this:

ps -ef | grep PROCESS | grep -v grep | awk '{print $2}' | xargs kill -9

kills all pids matching the search term of "PROCESS".

Answer 2

you can use killall which allows you to kill processes by name:

killall -ir example.jar

the options:

• -i : interactive (asks confirmation for each process whether or not to kill it)
• -r : allows you to specify a regex. killall will try to kill all matching.
