    19  ## Description
    20  
    21  The `docker kill` subcommand kills one or more containers. The main process
    22  inside the container is sent `SIGKILL` signal (default), or the signal that is
    23  specified with the `--signal` option. You can kill a container using the
    24  container's ID, ID-prefix, or name.
    25  
    26  > **Note**
    27  >
    28  > `ENTRYPOINT` and `CMD` in the *shell* form run as a child process of
    29  > `/bin/sh -c`, which does not pass signals. This means that the executable is
    30  > not the container’s PID 1 and does not receive Unix signals.

    32  ## Examples
    33  
    34  
    35  ### Send a KILL signal  to a container
    36  
    37  The following example sends the default `KILL` signal to the container named
    38  `my_container`:
    39  
    40  ```bash
    41  $ docker kill my_container
    42  ```
    43  
    44  ### Send a custom signal  to a container
    45  
    46  The following example sends a `SIGHUP` signal to the container named
    47  `my_container`:
    48  
    49  ```bash
    50  $ docker kill --signal=SIGHUP  my_container
    51  ```
    52  
    53  
    54  You can specify a custom signal either by _name_, or _number_. The `SIG` prefix
    55  is optional, so the following examples are equivalent:
    56  
    57  ```bash
    58  $ docker kill --signal=SIGHUP my_container
    59  $ docker kill --signal=HUP my_container
    60  $ docker kill --signal=1 my_container
    61  ```
    62  
    63  Refer to the [`signal(7)`](http://man7.org/linux/man-pages/man7/signal.7.html)
    64  man-page for a list of standard Linux signals.
