Down Boy! (Kill processes by Port)

#kill #port #pid #process

Need to kill processes by port? Try this...

Setup

Save this bash script as downboy to your bin directory:

#!/bin/bash
for PORT in $@
do
    PID=$(lsof -i :$PORT | awk 'FNR ==2 {print $2}')
    echo "kill -9 $PID"
    kill -9 $PID
done

Make downboy executable:

chmod +X ./downboy

Now you can easily close any number of processes by their port:

sudo downboy 80 8080 3000

Bye-bye.

Back in the mists of time, I recall that either the IRIX or Solaris implementation of fuser had the ability to kill processes by port.

Will save a lot of ps -ef | grep on my machine - I needed this, thanks!
