Yes, good. May I ask, why do you ask the user to enter the number of files first when you already know the simple, intuitive (and very commonly used) way like this for the user to indicate they're finished? If you need to know how many files they entered, you can do something like this:

while (<STDIN>) { chomp; last if $_ eq ''; push @files, $_; } printf "You entered %d files: { %s }\n", scalar @files, join(' ', @fil +es);

[marto]: I think you can do what you want without too much hassle, but yeah, please try and let me know if it works well :)
[marto]: sadly I've still not remembered the name of that x86 all in one we discussed
[Corion]: marto: Heh - I looked at the Intel things and they were all at EUR 80 or upwards, and that's a bit too much (or rather, for that money, I'd look for a NAS already)
[marto]: click bait marketing is making it harder to find stuff I can't remember based upon a few terms :(
[Corion]: :)
