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 container’s 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.
