Usage: docker diff CONTAINER
Inspect changes to files or directories on a container's filesystem
Options:
--help Print usage
```
## 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.
