In the Beginner Perl Maven video course we will mostly write Perl that are saved in files, but Perl can also be used on the command line, without saving the code in a file.

We are going to see an example here, and later on we are going to see a couple of more examples.

In order to open the command line, on Windows you need to click on Start/Run and then type in cmd. 

$ perl -v


$ perl -V


$ perl -e "print 42"

If running on perl 5.10 or later, you can also: 

$ perl -E "say 42"

On Unix/Linux you might prefer to use single quotes ' around the code: 

$ perl -E 'say 42'
