## 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:
|
|
|
|
```bash
|
|
$ ID=$(sudo docker run -d fedora /usr/bin/top -b)
|
|
|
|
$ sudo docker attach $ID
