This section provides notes to verify Perl version supported on macOS and run a simple Perl script.

macOS comes with Perl pre-installed. Here is what I did to verify the Perl version and program file location:

1. Start a Terminal and run "perl -v" to see the Perl version number:

herong$ perl -v

This is perl 5, version 18, subversion 2 (v5.18.2) built for ...
(with 2 registered patches, see perl -V for more detail)

Copyright 1987-2013, Larry Wall
...

2. Create a simple Perl script and run it:

herong$ cat > hello.pl
print "Hello world!\n";
Ctrl-d

herong$ perl hello.pl
Hello world!

Note that you need to press "Ctrl" and "d" together to end the input for the "cat" command.

3. Verify Perl program file locations:

herong$ which perl
/usr/bin/perl

herong$ ls -l /Library/Perl/
total 0
