Re: How do you simulate the use of the keyboard ?

If you prefer not changing your filehandle, you can also cat (or perhaps echo, if you're stuck in Windows land) a file into your script:

#!/usr/bin/perl -w

use strict;

print while (<STDIN>);

Invoke it like this: cat printline.pl | ./printline.pl This trick works really really well for debugging CGI.pm applications from the command line.
