It's not perfect. It's missing a close $fh and the substitution regexp probably should be s/\$([a-z]+)/ $vars{$1} || "\$$1" /gie; to give a somewhat sane behaviour for undefined variables (instead of substituting them with the empty string. Which is what *nix shells do, so I guess it's not that bad...)
