     9  [**-d**|**--detach**[=*false*]]
    10  [**--help**]
    11  [**-i**|**--interactive**[=*false*]]

    15  
    16  # DESCRIPTION
    17  
    18  Run a process in a running container. 
    19  
    20  The command started using `docker exec` will only run while the container's primary
    21  process (`PID 1`) is running, and will not be restarted if the container is restarted.
    22  
    23  If the container is paused, then the `docker exec` command will wait until the
    24  container is unpaused, and then run
    25  
    26  # OPTIONS
    27  **-d**, **--detach**=*true*|*false*
    28     Detached mode: run command in the background. The default is *false*.
    29  
    30  **--help**
    31    Print usage statement
    32  
    33  **-i**, **--interactive**=*true*|*false*
    34     Keep STDIN open even if not attached. The default is *false*.
    35  
    36  **-t**, **--tty**=*true*|*false*
    37     Allocate a pseudo-TTY. The default is *false*.
    38  
    39  **-u**, **--user**=""
    40     Sets the username or UID used and optionally the groupname or GID for the specified command.
    41  
    42     The followings examples are all valid:
    43     --user [user | user:group | uid | uid:gid | user:gid | uid:group ]
    44  
    45     Without this argument the command will be run as root in the container.
    46  
    47  The **-t** option is incompatible with a redirection of the docker client
    48  standard input.
