portdiscovery
Finds an open port (using portfinder) and sends output to stdout
npm install -g portdiscovery
Usage
Simply run portdiscovery
and it will look for open ports starting in 8000.
You can specify a base port if 8000
doesn't fit your needs: portdiscovery 8010
Cool tip
You can assign to a bash variable then use it to deploy your apps, for example:
httpPort=$(portdiscovery)echo $httpPort
