# kill
> Sends a signal to a process.
> Mostly used for stopping processes.
> 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.
- Kill the process:
- Terminate a program using the default SIGTERM (terminate) signal:
`kill {{process_id}}`
- List signal names:
- 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, it until a SIGCONT ("continue") signal is received:
`kill -{{17|STOP}} {{process_id}}`
