Actually, ".sh" does not appear to be a definitive declaration of the
scripting language.  However, if you deemed that to be a definitive
declaration for the scripting language the OP was using, then fine.

In any case, as I previously posted, it was left up to the OP to decide
if the proposed solution was suitable for their needs. After reading
all of the babble concerning what should be a relatively easy operation,
perhaps the OP might want to consider switching to Bash.
