There are many instances when we struggle to find out which port is being used by our applications.
On Windows, you can use the same netstat command, where the filtering is performed by findstr
netstat -an | findstr :80
Sample output on Windows:
C:\Users\sridharnetstat -an | findstr :80 TCP 0.0.0.0:8081 0.0.0.0:0 LISTENING TCP [::]:8081 [::]:0 LISTENING UDP 0.0.0.0:8082 *:* UDP [::]:8082 *:*
On Linux, you can use the following command. grep is basically a filter and in the below command, it filters the results with the keyword :80
netstat -an | grep :80
