# NAME
docker-attach - Attach to a running container
# SYNOPSIS
**docker attach** **--no-stdin**[=*false*] **--sig-proxy**[=*true*] CONTAINER
# DESCRIPTION
If you **docker run** a container in detached mode (**-d**), you can reattach to
the detached container with **docker attach** using the container's ID or name.
You can detach from the container again (and leave it running) with `CTRL-q
CTRL-q` (for a quiet exit), or `CTRL-c` which will send a SIGKILL to the
container, or `CTRL-\` to get a stacktrace of the Docker client when it quits.
When you detach from a container the exit code will be returned to
the client.
# OPTIONS
**--no-stdin**=*true*|*false*
When set to true, do not attach to stdin. The default is *false*.
**--sig-proxy**=*true*|*false*:
When set to true, proxify all received signal to the process (even in non-tty
mode). The default is *true*.
# EXAMPLES
## Attaching to a container
In this example the top command is run inside a container, from an image called
fedora, in detached mode. The ID from the container is passed into the **docker
attach** command:
# ID=$(sudo docker run -d fedora /usr/bin/top -b)
# sudo docker attach $ID
