## Command Description
|
|
|
|
This operation will calculate uniqueness and entropy of the media represented by a media dump image. It's not affected by the image format compression, if applicable.
|
|
|
|
## Command usage
|
|
|
|
```bash
|
|
Aaru -d [true/false] -v [true/false] image entropy -h [true/false] -p [true/false] -t [true/false] -w [true/false] <image-path>
|
|
```
|
|
|
|
`-d, --debug [true/false]` shows debug output *(default false)*
|
|
`-v, --verbose [true/false]` shows verbose output *(default false)*
|
|
`-h, --help [true/false]` shows help screen for the command instead of running it, ignores all other switches *(default false)*
|
|
`-p, --duplicated-sectors [true/false]` besides entropy also calculates how many sectors have the exact same data in their user area *(default true)*
|
|
`-t, --separated-tracks true/false]` separately calculates the entropy for each track dividing the media. Only applicable to certain kind of media (optical discs and digital tapes mostly) *(default true)*
|
|
`-w, --whole-disc [true/false]` calculates the entropy for the whole media *(default true)*
|
|
|
|
## Example
|
|
|
|
```bash
|
|
Aaru image entropy mydisc.cue
|
|
```
