How to display only PID using netstat?

Question

linux

Command: netstat -tulpn | grep :25598
Output: udp 0 0 192.168.0.100:25598 0.0.0.0:* 5813/hlds_linux
As I understood 5813 is the PID of the process, how can I make it so that only the PID is output?
That is: 5813

Answer 1

sudo netstat -tulpn | grep:25598 | awk '{print $7}' | cut -d'/' -f1
But it's better to look in the daemon's pid file :)
