BASH script for deploying WordPress content changes from staging to production

deploy.sh

#!/bin/bash
# A BASH script for deploying WordPress content changes 
# from staging to production. Note: this works for me because both my
# staging and production share the same plugins folder, and I have permissions
# on all the appropriate directories to allow the user running the script to
# perform all the actions in here. May need tweaking for other setups.
