Tried using strict? It's a good habit to aquire.
I think what you're trying to do can be done with this:
open(NB, "nbt.csv") or die "Error reading nbt.csv: $!\n";
@nbtstat = `nbtstat -a $_`;
As I understand it, you want:
- nbtstat each IP address in the file (hopefully XXX.XXX.XXX.XXX, 15 chars ;)
Make a list of unique IP addresses (found at the beginning of each line returned)
- Print the list to STDOUT comma seperated
Or have I got the wrong end of the stick?
Note: this'll print the original IP address twice.
