After accidentally pushing a development branch out to production (fortunately no problems, just unexpected new features for users) I decided to proactively prevent it happening again with a simple bit of bash and git.

deploy-master

#!/bin/bash
# We only run the deployment if we're already on master; we could do this directly in gulp but it allows for other commands to be added

if [ $(git rev-parse --abbrev-ref HEAD) == "master" ]; then

	gulp deploy

else

	echo "Must be on master"
