* Fix ShellCheck warning 2219 https://github.com/koalaman/shellcheck/wiki/SC2219 * Replace GNU sed commands with perl This replaces the sed commands which required GNU sed be installed with perl versions. This should make this script more universally usable (e.g., on macOS) without installing additional tools.
