Terminate a program by port on Mac

Sometimes I need to kill a process. I always have to Google how to do that again. Not anymore. Put this function in ~/.bash_profile.

# terminate function
terminate () {
  lsof -i "tcp:$1" | tail -1 | awk '{print $2}' | xargs kill -9 && echo "Killed proces on port $1" || echo "Failed to kill proces on port $1"

So now you can type terminate 3000 to kill the process on port 3000

Happy coding! – Found a mistake or a typo? Please submit a PR to my GitHub-repo.
