# kill
```markdown
Usage: docker kill [OPTIONS] CONTAINER [CONTAINER...]
Kill one or more running containers
Options:
--help Print usage
-s, --signal string Signal to send to the container (default "KILL")
```
## Description
The `docker kill` subcommand kills one or more containers. The main process
inside the container is sent `SIGKILL` signal (default), or the signal that is
specified with the `--signal` option. You can kill a container using the
container's ID, ID-prefix, or name.
> **Note**: `ENTRYPOINT` and `CMD` in the *shell* form run as a subcommand of
> `/bin/sh -c`, which does not pass signals. This means that the executable is
> not the containers PID 1 and does not receive Unix signals.
## Examples
### Send a KILL signal to a container
The following example sends the default `KILL` signal to the container named
`my_container`:
```bash
$ docker kill my_container
```
### Send a custom signal to a container
The following example sends a `SIGHUP` signal to the container named
`my_container`:
```bash
$ docker kill --signal=SIGHUP my_container
```
You can specify a custom signal either by _name_, or _number_. The `SIG` prefix
is optional, so the following examples are equivalent:
```bash
$ docker kill --signal=SIGHUP my_container
$ docker kill --signal=HUP my_container
$ docker kill --signal=1 my_container
```
Refer to the [`signal(7)`](http://man7.org/linux/man-pages/man7/signal.7.html)
man-page for a list of standard Linux signals.
