How do I pass a parameter to a Perl script?
If you want to use the two arguments as input files, you can just pass them in and then use <> to read their contents. Alternatively, @ARGV is a special variable that contains all the command line arguments. $ARGV[0] is the first (ie. “string1” in your case) and $ARGV[1] is the second argument.

- Find the interpreter/executors path. In this case its /usr/bin/perl or /usr/bin/env perl.
- Add it to the first line of the file as #!/usr/bin/perl .
- Give execute permission to the file chmod +x example.pl.
