How many times did you tried to search how to find the PID for process which is running in a specific port. I face this problem at least once per week. Sometimes I close VS Code directly without closing the running processes from integrated terminal.
The command below works perfectly for Linux and MAC OS users
lsof -n -i :PORT
For example, if you’re trying to find the PID of the process running on port
3000 simply run this:
lsof -n -i :3000
Explanation of command
Let’s come back to our command and see how exactly get the PID for the port specified:
-n no host names -i i select by IPv address: [proto][@host|addr][:svc_list|port_list]
