here is what i did on a command line on a linux box with bash a few standard commands

for x in `seq -99 -1| sed s/-//`;do echo $x bottles of beer on the wall, $x bottles of beer, take one down, pass it around... $x bottles of beer on the wall;done

@David:
Why in the world would you do that rather than just:

for x in {99..1}; do ...; done

Or alternatively:

for (x=99; x>0; x++); do ...; done

They need an edit comment feature on this site. :P Or at least a preview before posting.

Anyhow, x-- not x++. Oops.
