# This shell script is an optional tool to simplify
# the installation and usage of laradock with docker-sync.

# Make sure that the DOCKER_SYNC_STRATEGY is set in the .env
# DOCKER_SYNC_STRATEGY=native_osx # osx
# DOCKER_SYNC_STRATEGY=unison # windows

# To run, make sure to add permissions to this file:
# chmod 755 sync.sh

# USAGE EXAMPLE:
# Install docker-sync: ./sync.sh install
# Start sync and services with nginx and mysql: ./sync.sh up nginx mysql
# Stop containers and sync: ./sync.sh down
# Open bash inside the workspace: ./sync.sh bash
# Force sync: ./sync.sh sync
# Clean synced files: ./sync.sh clean

# prints colored text
