I did "apt-get --help" and at the end of the output it said "This APT has Super Cow Powers." I have never seen this message before. Can anyone tell me what it means? Thanks ahead of time for your input.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

And my aptitude does not have super cow powers – daithib8 Mar 2 '12 at 16:10
Actually aptitude has super duper cow farm powers. Do this aptitude -v moo. Afterwards starting adding V's like aptitude -vvv moo and keep doing this until "something" happens. – Luis Alvarado Mar 2 '12 at 16:21

@jokerdino, jrg You should probably add this as an answer to the "duplicate" question now. There's currently no mention on that page of what was asked about here. – ændrük Mar 2 '12 at 19:43

It appears to be a joke.

According to Wikipedia's article on aptitude, apt-get contains an easter egg resembling cowsay that can be found by issuing the moo command:

$ apt-get moo
  / |    ||
 *  /\---/\
    ~~   ~~
...."Have you mooed today?"...

The line in its help output,

$ apt-get --help | grep 'Super Cow Powers'
                       This APT has Super Cow Powers.

is presumably a reference to this easter egg, or perhaps was added later to parallel aptitude's claim that it "does not have Super Cow Powers".

Interestingly, aptitude moo spits out: There are no Easter Eggs in this program. – Ads20000 Apr 22 '14 at 13:11
