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

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

Aaru image entropy mydisc.cue
