Setting up (what you'll need)

To run Perl you will need the following. Perl is a language strong in string handling and regular expressions, and has long been used for log analysis, text processing, and web back ends (CGI).

• Perl itself: it is usually installed by default on Mac and Linux. On Windows, use something like Strawberry Perl.
• Typing perl -v in a terminal shows you the version.
• For an editor, the easiest route is VS Code with a Perl extension.
