==Command description==
This operation will calculate uniqueness and entropy of the media represented by a media dump image. It's not affected my the image format compression if applicable.
==Command usage==
<code>DiscImageChef entropy -i <dump> -v [true/false] -d [true/false] -p [true/false] -t [true/false] -w [true/false]</code>
<code>-i, --input=<dump></code> path to the media dump image<br />
<code>-v, --verbose=[true/false]</code> shows verbose output ''(default false)''<br />
<code>-d, --debug=[true/false]</code> shows debug output ''(default false)''<br />
<code>-p, --duplicated-sectors=[true/false]</code> besides entropy also calculates how many sectors have the exact same data in their user area ''(default true)''<br />
<code>-t, --separated-tracks=[true/false]</code> 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)''<br />
<code>-w, --whole-disc=[true/false]</code> calculates the entropy for the whole media ''(default true)''
==Example==
<code>DiscImageChef entropy -i mydisc.cue</code>

# Command usage
DiscImageChef entropy -i \<dump\> -v [true/false] -d [true/false] -p [true/false] -t [true/false] -w [true/false]
-i, --input=\<dump\> path to the media dump image
-v, --verbose=[true/false] shows verbose output _[default false]_
-d, --debug=[true/false] shows debug output _[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]_
