     4  # NAME
     5  docker-attach - Attach to a running container
     6  
     7  # SYNOPSIS
     8  **docker attach**
     9  [**--no-stdin**[=*false*]]
    10  [**--sig-proxy**[=*true*]]
    11  CONTAINER
    12  
    13  # DESCRIPTION
    14  If you **docker run** a container in detached mode (**-d**), you can reattach to
    15  the detached container with **docker attach** using the container's ID or name.
    16  
    17  You can detach from the container again (and leave it running) with `CTRL-p 
    18  CTRL-q` (for a quiet exit), or `CTRL-c`  which will send a SIGKILL to the
    19  container, or `CTRL-\` to get a stacktrace of the Docker client when it quits.
    20  When you detach from a container the exit code will be returned to
    21  the client.
    22  
    23  It is forbidden to redirect the standard input of a docker attach command while
    24  attaching to a tty-enabled container (i.e.: launched with -t`).
    25  
    26  # OPTIONS
    27  **--no-stdin**=*true*|*false*
    28     Do not attach STDIN. The default is *false*.
    29  
    30  **--sig-proxy**=*true*|*false*
    31     Proxy all received signals to the process (non-TTY mode only). SIGCHLD, SIGKILL, and SIGSTOP are not proxied. The default is *true*.
    32

    35  ## Attaching to a container
    36  
    37  In this example the top command is run inside a container, from an image called
    38  fedora, in detached mode. The ID from the container is passed into the **docker
    39  attach** command:
    40  
    41      # ID=$(sudo docker run -d fedora /usr/bin/top -b)
    42      # sudo docker attach $ID
