Linux grep all running processes for a given port and kill them

Open a terminal and type the command:

• netstat -anp | grep 8080

Replace 8080 with your desired port.

You will get a result like below

• tcp6     0     0 :::8080      :::*     LISTEN      6903/java 

The 6903 is your process id.

Optionally if you want to kill this process, type the command

• kill -9 6903
