in reply to expanding variables in variables

Can't you drop the split with qx?
In scalar context, it comes back as a single (potentially multi-line) string, or undef if the command failed. In list context, returns a list of lines (however you've defined lines with $/ or $INPUT_RECORD_SEPARATOR), or an empty list if the command failed.

    Yup, but then the \n is still at the end of each line then, so you need to chop or chomp the array to get the same result.
