     4  # NAME
     5  docker-attach - Attach to a running container
     6  
     7  # SYNOPSIS
     8  **docker attach**
     9  [**--help**]/
    10  [**--no-stdin**[=*false*]]
    11  [**--sig-proxy**[=*true*]]
    12  CONTAINER
    13  
    14  # DESCRIPTION
    15  The **docker attach** command allows you to attach to a running container using
    16  the container's ID or name, either to view its ongoing output or to control it
    17  interactively.  You can attach to the same contained process multiple times
    18  simultaneously, screen sharing style, or quickly view the progress of your
    19  daemonized process.
    20  
    21  You can detach from the container (and leave it running) with `CTRL-p CTRL-q`
    22  (for a quiet exit) or `CTRL-c` which will send a `SIGKILL` to the container.
    23  When you are attached to a container, and exit its main process, the process's
    24  exit code will be returned to the client.
    25  
    26  It is forbidden to redirect the standard input of a `docker attach` command while
    27  attaching to a tty-enabled container (i.e.: launched with `-t`).
    28  
    29  # OPTIONS
    30  **--help**
    31    Print usage statement
    32  
    33  **--no-stdin**=*true*|*false*
    34     Do not attach STDIN. The default is *false*.
    35  
    36  **--sig-proxy**=*true*|*false*
    37     Proxy all received signals to the process (non-TTY mode only). SIGCHLD, SIGKILL, and SIGSTOP are not proxied. The default is *true*.

    41  ## Attaching to a container
    42  
    43  In this example the top command is run inside a container, from an image called
    44  fedora, in detached mode. The ID from the container is passed into the **docker
    45  attach** command:
    46  
    47      # ID=$(sudo docker run -d fedora /usr/bin/top -b)
    48      # sudo docker attach $ID
