Bash Question

I'm trying to do a somewhat of a variable substitution operation.
I need to calculate the second to last variabe in the script. This is done by various ways most involving "$# - 2", now my question is how do I make the output of such operations to calculate "$# - 2" as a suffix to $ to be taken as a variable?

Use Ruby.

He asked about bash.

Not everything can be done in bash.

Variables are ordered? I thought they had "names."

Use PHP (CLI SAPI), it's great for that kind of thing, portable, quicker than Ruby or Python and nicer than Perl.

He means runtime parameters in bash they're $1 $2 $3 ...

PHP quicker than Ruby or Python (or any language)? I don't think so.

Can I enlarge my penis using bash?

Sure. Lay your dick down on a desk and bash it with a hammer. You won't be able to get it up anymore, but the girls will be amazed by your newly inflamed bleeding dick.

Bonus points: it's about as enjoyable as programming in bash as well. And more productive!

PHP seems to perfrom faster than Ruby, but by quicker I meant faster to get a short system script done on PHP than Ruby or Python.
