I know I can get
a="abcdef" echo "${a[2:4]}" = cde

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 address@hidden:1:2}


I see little reason to ask bash to wordsplit the elements after expanding them.


You ought to quote that expansion.

    Good point.

Since if you do:

4
#yikes!
> b=( "address@hidden:1:2}" )
2
#woo!

I'd guess the original poster probably figured, I'd figure out the correct
form pretty quickly in usage.  but thanks for your insight.

( (to all)....*sigh*)


I "always" quote not sure why I didn't that time.
Except that it was just a quick response to a simple question.
but of course your right.
