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);

[Discipulus]: both: everyting must be identical in the new v-machine
[Lady_Aleena]: So putting a nice DE or WM up on a Linux machine is not an option?
[Discipulus]: i need some converter to have directly an OVF format directly: at the moment i'm trying with vmware converter standalone
[Lady_Aleena]: I don't know what to tell you. I can barely get my Linux machine to do things I want.
[Discipulus]: if DE or WM means desktop env and win manager.. no, not an option
[Lady_Aleena]: That's what they mean, at least to me. 8)
[Discipulus]: in the first attempt i failed, with an not usable v-machine.. ;=)
[Discipulus]: but then discovered a registry trick to do before the physical2virtual migration
[Lady_Aleena]: Sounds like a headache.
