How to expand array content from its name?

I have an array declare -a arr0=("'1 2 3'" "'4 5 6'") and a variable x=0 Then I create the new variable with the array's name tmp="arr$x" and I'd like to be able to expand arr0 content from this tmp variable like this newArr=( "${!tmp}" ) and to use newArr like the ordinary array, e.g. use indices etc. --- But when I try print it now, it looks like this: $ echo ${newArr[@]} '1 2 3' Only the first element is stored and I don't know, how to fix it. I've also tried to create newArr like this newArr=( "${!tmp[@]}" ) but then it's even worse - only 0 is printed. $ echo ${newArr[@]} 0 --- So, do you know, how to use an array if its name is stored in some other variable?
