thanks, so as far as I understand using FILE descriptor is the best solution, right?

as for awk, uniq and sort bash commands, what is the equivalent in perl for that functions, or should I use regexp?

for example: I need to sort IPs from netstat command, look: 
# netstat -ntu | egrep 'udp|tcp' | awk '{print $4}' | sort | uniq -c |
+ sort -nr

how can I do the same using just perl functions?

Is it better to use perl native functions for such purpose instead of calling external shell commands?
