Description
Trying to automate information manipulation using docker cli is complicate as parameters such as human=false or no-trunc are not available consistently.
To give some examples:
- image history
- image inspect
- image ls
- system df
- human=false is available on 1 but not 2, 3 and 4, forcing to parse a formatted value
- no-trunc is required to have complete ID's in 1 and 3 while not needed in 2 and 4
In addition UniqueSize reported by 4 is often 0 as shown in the excerpt below (the first value after "image" is supposed to be the UniqueSize).
