    17  # DESCRIPTION
    18  
    19  Run a process in a running container. 
    20  
    21  The command started using `docker exec` will only run while the container's primary
    22  process (`PID 1`) is running, and will not be restarted if the container is restarted.
    23  
    24  If the container is paused, then the `docker exec` command will wait until the
    25  container is unpaused, and then run
    26  
    27  # OPTIONS
    28  **-d**, **--detach**=*true*|*false*
    29     Detached mode: run command in the background. The default is *false*.
    30  
    31  **--help**
    32    Print usage statement
    33  
    34  **-i**, **--interactive**=*true*|*false*
    35     Keep STDIN open even if not attached. The default is *false*.
    36  
    37  **--privileged**=*true*|*false*
    38     Give extended privileges to the process to run in a running container. The default is *false*.
    39  
    40     By default, the process run by docker exec in a running container
    41  have the same capabilities of the container. By setting --privileged will give
    42  all the capabilities to the process.
    43  
    44  **-t**, **--tty**=*true*|*false*
    45     Allocate a pseudo-TTY. The default is *false*.
    46  
    47  **-u**, **--user**=""
    48     Sets the username or UID used and optionally the groupname or GID for the specified command.
    49  
    50     The followings examples are all valid:
    51     --user [user | user:group | uid | uid:gid | user:gid | uid:group ]
    52  
    53     Without this argument the command will be run as root in the container.
    54  
    55  The **-t** option is incompatible with a redirection of the docker client
    56  standard input.
