    31  By default the command will just show a summary of the data used:
    32  ```bash
    33  $ docker system df
    34  TYPE                TOTAL               ACTIVE              SIZE                RECLAIMABLE

    65  * `SHARED SIZE` is the amount of space that an image shares with another one (i.e. their common data)
    66  * `UNIQUE SIZE` is the amount of space that is only used by a given image
    67  * `SIZE` is the virtual size of the image, it is the sum of `SHARED SIZE` and `UNIQUE SIZE`
    68  
    69  Note that network information is not shown because it doesn't consume the disk space.
