Prefix and postfix elements of a bash array

Question

I want to pre- and postfix an array in bash similar to brace expansion.

Say I have a bash array

ARRAY=( one two three )

I want to b

Answer 1

I have exactly the same question, and I come up with the following solution using sed's word boundary match mechanism:

myarray=( one two three )
newarray=( $(echo ${myarray[*]}|sed "s/\(\b[^ ]\+\)/pre-\1-post/g") )
echo ${newarray[@]}
> pre-one-post pre-two-post pre-three-post
echo ${#newarray[@]}
> 3

Waiting for more elegant solutions...
