`pkill "{{process_name}}"`
- Kill all processes which match their full command instead of just the process name:
`pkill {{[-f|--full]}} "{{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}}"`
