First off, when assigning variables in Unix shell, you don't start with a '$', so you're really looking at starting out with

Next, if you want simple integer-indexed arrays, the shell can do this directly.


  echo ${TEST[$INDEX]}

The main limitation is that the index must be in the set 0...10 on some older shell implementations.

Meanwhile, if you truely want to do $VAR$INDEX, then the follwoing syntax is what you want...

eval echo "$`echo "$VAR$INDEX"`"
