Problem

How to use the killall command: Send kill signal to all instances of a process by name (must be exact name). All signals except SIGKILL and SIGSTOP can be intercepted by the process, allowing a clean exit. More information: <https://manned.org/killall>.

Solution

killall — Send kill signal to all instances of a process by name (must be exact name). All signals except SIGKILL and SIGSTOP can be intercepted by the process, allowing a clean exit. More information: <https://manned.org/killall>.

Terminate a process using the default SIGTERM (terminate) signal:

killall {{process_name}}

List available signal names (to be used without the SIG prefix):

killall {{[-l|--list]}}

Interactively ask for confirmation before termination:

killall {{[-i|--interactive]}} {{process_name}}

Terminate a process using the SIGINT (interrupt) signal, which is the same signal sent by pressing <Ctrl c>:

killall -INT {{process_name}}

Force kill a process:

killall -KILL {{process_name}}
