Best way to open and run Pearl scripts on Mac, running Big sur?

Perl has traditionally been a scripting language used on the command-line of Linux and Unix environments, and since macOS is built on top of a flavor of Unix called BSD, it ships with everything needed to write and run Perl scripts, including a handy command-line environment called Terminal. Thus, you can easily run your Perl script in Terminal by invoking it on the command line.

To do so, open Terminal by navigating to your Applications folder (in Finder), then to the Utilities folder, and then to the Terminal application. Once opened, go back to Finder, highlight the Perl script you wish to run, and press Cmd+C to copy the full path of the highlighted script to the clipboard. Next, return to Terminal, type "perl" followed by a blank space, and press Cmd+V to paste the full path of your script into the Terminal window. Finally, press the Enter or Return key to execute the script.

Note: If you know your script will need administrator privileges, type the word "sudo" followed by a blank space before you type "perl" and paste the path to your script (see above). When you press Enter or Return, you will be prompted for your current macOS user password and then, if entered correctly, the script will execute with administrator privileges. Be aware that, as a security measure, no text will be displayed on-screen while entering your password.

For additional information about running Perl scripts on the command line, type "man perl" into an open Terminal window and then press Enter or Return to display the Perl 5 Language Interpreter manual page.
