Deploy Script on Forge:

cd /home/forge/{site}
git pull origin develop

deploy_script {site}

You could use this script for Laravel apps as well. Just add your commands on line 52.

sorry for the noob comment but I wanted to ask how to use this. I tried to command deploy_script but it says command not found.

It's not a 'noob' comment 😄! What you do (or at least I did) is the following:

1. Create a folder in your /home/forge directory named .bin, so the absolute path: /home/forge/.bin
2. Put the file there, so the path is: /home/forge/.bin/deploy_site
3. Add execute rights to the file: chmod +x /home/forge/.bin/deploy_site (you might need sudo for this)
4. Add the folder to your path to execute the command from everywhere: export PATH=$PATH:/home/forge/.bin.
5. Change your deployment script in forge:

cd /home/forge/domain.com
git pull origin master

deploy_script domain.com

I hope this helps you out!
