## Description
|
|||
|
|
|
|||
|
|
List the changed files and directories in a container᾿s filesystem since the
|
|||
|
|
container was created. Three different types of change are tracked:
|
|||
|
|
|
|||
|
|
| Symbol | Description |
|
|||
|
|
|--------|---------------------------------|
|
|||
|
|
| `A` | A file or directory was added |
|
|||
|
|
| `D` | A file or directory was deleted |
|
|||
|
|
| `C` | A file or directory was changed |
|
|||
|
|
|
|||
|
|
You can use the full or shortened container ID or the container name set using
|
|||
|
|
`docker run --name` option.
