Previously, we have discussed the Easiest Way To Install Perl on Windows and Easiest Way to Run Perl Script on Windows but question is how to save a perlscript. No doubt, you need a text editor like Textpad (my favorite) to write down your perlscript. After typing the code given below just save the file with the extention ".pl" means if youe file name is "input" then save the file as "input.pl" and you are done. 

#!/usr/local/bin/perl
print "Hello, EduGirl!\n";
