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}}
• [l]ist available signal names (to be used without the 'SIG' prefix):
  killall -l
• Interactively ask for confirmation before termination:
  killall -i {{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}}
