# kill
|
|
|
|
> Send 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 {{[-19|-STOP]}} {{process_id}}`
|
|
|
|
- Send a `SIGUSR1` signal to all processes with the given GID (group id):
|
|
|
|
`kill -SIGUSR1 -{{group_id}}`
