Shell script Kill (Kill) port number corresponding to the PID process

I use the Mac is when you start a Python port process, even if it is turned off, the background process is still present, the process of initiating the same port, or the error prompt has been occupied

When you lsof-i: the port number (linux--(SS-ANPT | grep)--(SS is shorthand for Nestat), and you will find that a PID process kill is troublesome, so write a shell script, according to the port number you entered, Cycle kill :

#!/bin/""  afor inawk'{print $'grep'PID';  Do Kill -9 $i;  Done
