Sometimes I leave processes running which take up ports on my local machine (e.g., Redis server). I won’t be able to use the port until it’s freed up, but it’s sometimes a chore to figure out how to kill the process by port.
I found the following snippet super useful to kill a process by port in Mac OS:
lsof -t -i tcp:[port] | xargs kill
Just replace the [port] above with the actual numbered port (e.g., 6379).
