How to kill all processes with the same name?

Question

I want to kill all processes with the same name that belong to a user, for example:

$ps -u user_1
2345 myapp
2346 myapp
2347 myapp
2348 myapp2
2349 myapp

I want to kill all "myapp" processes that belong to "user_1", how can I do this?

Answer 1

You can use the pkill command.

pkill -u user_1 myapp

Note that myapp2 won't be killed as it has a different name.

Answer 2

use pkill command and wild cards

pkill -u user_name 'myap*'

it will kill all processes starting with myap.
