<> will read from the files specified as arguments I believe. I do
this:
print "Would you like to remove this file? (Y/N) ";
my $input = <STDIN>;
if ($input =~ /^[yY]$/) {
unlink($filename) && print "File '$filename' has been deleted.\n";
}
This requires the user to hit y or Y and then ENTER. It is possible to
do this without the enter but it takes more work.
