kill

Sends a signal to a process, usually related to stopping the process. All signals except for SIGKILL and SIGSTOP can be intercepted by the process to perform a clean exit. More information: <https://manned.org/kill.1posix>.

  • Terminate a program using the default SIGTERM (terminate) signal:
    kill process_id
  • List available signal names (to be used without the `SIG` prefix):
    kill -l
  • Terminate a program using the SIGHUP (hang up) signal. Many daemons will reload instead of terminating:
    kill -1|HUP process_id
  • Terminate a program using the SIGINT (interrupt) signal. This is typically initiated by the user pressing `Ctrl + C`:
    kill -2|INT process_id
  • Signal the operating system to immediately terminate a program (which gets no chance to capture the signal):
    kill -9|KILL process_id
  • Signal the operating system to pause a program until a SIGCONT ("continue") signal is received:
    kill -17|STOP process_id
  • Send a `SIGUSR1` signal to all processes with the given GID (group id):
    kill -SIGUSR1 -group_id
