How do I kill the process currently using a port on localhost in Windows?

Question

How can I remove the current process/application which is already assigned to a port?

For example: localhost:8080

Answer 1

In Windows PowerShell version 1 or later to stop a process on port 3000 type:

Stop-Process (,(netstat -ano | findstr :3000).split() | foreach {$[$.length-1]}) -Force

As suggested by @morganpdx here`s a more PowerShell-ish, better version:

Stop-Process -Id (Get-NetTCPConnection -LocalPort 3000).OwningProcess -Force

Answer 2

One line solution using GitBash:

 tskill `netstat -ano | grep LISTENING | findstr :8080 | sed -r 's/(\s+[^\s]+){4}(.*)/\1/'`

Replace 8080 with the port your server is listening to.

If you need to use it often, try adding to your ~/.bashrc the function:

function killport() {
        tskill `netstat -ano | findstr LISTENING | findstr :$1 | sed -r 's/^(\s+[^\s]+){4}(\d*)$/\1/'`
}

and simply run

killport 8080
