pkill

Signal process by name.

Mostly used for stopping processes.

• Kill all processes which match:

pkill "{process_name}"

• Kill all processes which match their full command instead of just the process name:

pkill -f "{command_name}"

• Force kill matching processes (can't be blocked):

pkill -9 "{process_name}"

• Send SIGUSR1 signal to processes which match:

pkill -USR1 "{process_name}"

• Kill the main `firefox` process to close the browser:

pkill --oldest "{firefox}"
