If you liked my post about fun terminal commands, you’ll also probably enjoy this one.


If you ever noticed that apt --help ends with:

This APT has Super Cow Powers.

you probably wondered what on earth that means. Well, the command apt moo may shed some light on this:

          / |    ||   
         *  /\---/\ 
            ~~   ~~   
..."Have you mooed today?"...


On the subject of moos, aptitude --help contains:

This aptitude does not have Super Cow Powers.

So, if you run aptitude moo, you get:

There are no Easter Eggs in this program.

I think not aptitude -v moo:

There really are no Easter Eggs in this program.

I’m not so sure aptitude -vv moo:

Didn't I already tell you that there are no Easter Eggs in this program?

Yes, but aptitude -vvv moo:

Stop it!

Why? aptitude -vvvv moo:

Okay, okay, if I give you an Easter Egg, will you go away?

Maybe aptitude -vvvvv:

All right, you win.

                       -------/      \
                      /               \
                     /                |
   -----------------/                  --------\

Yay! One more aptitude -vvvvvv moo

What is it?  It's an elephant being eaten by a snake, of course.

Ok, fine.

For you vim fans:

If you’ve ever pondered the meaning of life, run vim, and then :help 42:

What is the meaning of life, the universe and everything?  *42*
Douglas Adams, the only person who knew what this question really was about is
now dead, unfortunately.  So now you might wonder what the meaning of death

This is fun if you’re ever using a mac as emacs is built in to the terminal, I think. There are quite a few programs built in, which you can list with:

ls /usr/share/emacs/*/lisp/play

I got:

5x5.elc       dissociate.elc  gomoku.elc     mpuz.elc       tetris.elc
animate.elc   doctor.elc      handwrite.elc  pong.elc       zone.elc
blackbox.elc  dunnet.elc      hanoi.elc      snake.elc
bubbles.elc   fortune.elc     landmark.elc   solitaire.elc
cookie1.elc   gamegrid.elc    life.elc       spook.elc
decipher.elc  gametree.elc    morse.elc      studly.elc

I like pong, so I ran emacs, then Esc followed by x, then pong. I also tried tetris. My favorite was doctor(what I type begins with a --):

I am the psychotherapist.  Please, describe your problems.  Each time
you are finished talking, type RET twice.
-- I like pie. RET RET

Why do you say you like pie ret ret?
-- Why not?

What do you think?
-- Pie tastes good.

Is it because of your plans that you say pie tastes good?
-- No, are you even paying attention?

Maybe your life has something to do with this.
-- No, really?

What makes you believe really?
-- yes

I see...  Well, are you sure that this is so?
-- yes

Yes, hmmm... so, do you really think this is so?
-- yes

I understand.  So what makes you think this is so?

and I got bored.
