Regarding quotes, the OP might find a module that provides shell escaping useful. Such as String::ShellQuote.
printf is probably more surefire than echo there:
printf "%s" "$cmd" | grep -e '----'But shelling out is very error-prone (as the OP discovered) and pretty vain when the code can be reproduced in Perl in a few lines.
