    27  ## Description
    28  
    29  List the changed files and directories in a container᾿s filesystem since the
    30  container was created. Three different types of change are tracked:
    31  
    32  | Symbol | Description                     |
    33  |--------|---------------------------------|
    34  | `A`    | A file or directory was added   |
    35  | `D`    | A file or directory was deleted |
    36  | `C`    | A file or directory was changed |
    37  
    38  You can use the full or shortened container ID or the container name set using
    39  `docker run --name` option.
    40
