killall

Use

ps -u "$USER" -o pid,comm,args
killall -TERM exact-process-name

What It Does

killall sends a signal to processes by name.

Practice

Prefer kill with a process id while learning. Use killall only when the process name is exact, unambiguous, and you have checked what matches.

ps -u "$USER" -o pid,comm,args
killall -TERM exact-process-name

Watch Out

Process names can match more than you intended. Do not run broad commands like killall python3 on the shared server; several unrelated tools can use Python.

Docs Pointers

• Run man killall.
