I know your question has been probably answered :).
However, if I may draw your attention to some stuff in your code:
would fail to do what you intended, in case your file doesn't exists.
open FILE, "<hostname_check.txt" || die $!;
It's better written as
open ( FILE, "<hostname_check.txt" ) || die $!;
open FILE, "<hostname_check.txt" or die $!;
- Use lexically scoped filehanles and the 3-argument open function like so:
open my $fh, '<',"hostname_check.txt" or die $!;
- Also check the return of close function
If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
