I know I can get

how do I do:
typeset -a a=(apple berry cherry date); then get:
echo ${a[1:2]} = "berry" "cherry" ( non-grouped args)
I tried to do it in a function and hurt myself.
echo ${a[@]:1:2}

You ought to quote that expansion.

#yikes!

#woo!
I'd guess the original poster probably figured, I'd figure out the correct
