sudo aptitude help aptitude 0.4.11.11 Usage: aptitude [-S fname] [-u|-i] aptitude [options] <action> ... Actions (if none is specified, aptitude will enter interactive mode): ... This aptitude does not have Super Cow Powers.
I think it's referring to
$ apt-get moo (__) (oo) /------\/ / | || * /\---/\ ~~ ~~ ...."Have you mooed today?"...
To quote Wikipedia:
aptitude states that, unlike Advanced Packaging Tool, it "does not have Super Cow Powers". In apt-get "super cow powers" can be found by issuing the command
apt-get moo. However, in aptitude issuing moo will give the user a prompt saying there are no easter eggs.
However, by issuing
aptitude -v moo, then
aptitude -vv moo, and so on the user will see a series of statements telling them to go away, some ending with a picture not unlike the original apt-get easter egg. Different versions of the program have different sequences.
And, as wRAR commented, the term “Super Cow Powers” is a direct quote from
This APT has Super Cow Powers.
Not so well known, but there is also

Cows have been hidden as easter eggs in pinball games.
