bash - Passing arrays into for-loop variable?

[j.patton]

Perhaps it would be easiest to show you what I'm trying to do with the code and output...

#!/bin/sh

national=( "us_radar" "-120,26" "-60,52" "1500" "650" )
iowalocal=( "iowa" "-99.25,37.5" "-87.25,45.5" "900" "600" )

echo ${#national[*]}
echo ${#iowalocal[*]}

for site in ${national} ${iowalocal}; do

    echo ${#site[*]}

done

Output:

5
5
1
1

I've verified that national[0] or iowalocal[0] is the one item that actually gets passed into site. Is there some way to pass entire arrays into a for-loop variable? I can restructure my code with five arrays instead and just do for num = 0 1 etc., but that's a bit messy for this script's purpose.

Thanks for any help you can provide!

To print the elements of an array you can do something like:

for i in $(seq 0 $((${#national[*]} - 1)))
do
  echo "${national[$i]}"
done
