You have to remember that referencing an array variable without using
[EMAIL PROTECTED] will always return the first element of the array. Indirect
variable expansion cannot be coerced to do otherwise.
You can always use `eval' to force the sort of double expansion you
want. Just remember to quote everything whose evaluation you want
deferred:
DIRS_name1=( /foo /bar /baz )
DIRS_name2=( /qux /quux )
name=${1:-name1}
v=DIRS_$name
eval a='( "${'$v'[EMAIL PROTECTED]" )'
echo [EMAIL PROTECTED]
