Ghost CMS upgrade - script for lazy admins

New version of that entry

I made short script for easier upgrade of Ghost (self hosted version). At the moment Ghost is still in development before version 1.0 so there is no official script for upgrade.
I took steps from Ghost blog wiki http://support.ghost.org/how-to-upgrade and combined them in a bash script for easier use.

I am not an author or contributor of Ghost blog.

#!/bin/bash
export path_to_ghost_install="/path/to/ghost/install"
export ghost_service="ghost_service_name"
## go to your home
cd ~
## Get the latest version:
curl -LOk https://ghost.org/zip/ghost-latest.zip
## Unzip to a temporary location:
unzip ghost-latest.zip -d ghost_temp
## make a backup of ghost install
service $ghost_service stop
cp -R $path_to_ghost_install ghost_temp/backup
## Change directory into your current ghost install:
cd $path_to_ghost_install
## Remove the core directory:
rm -rf core
## Change back to your download of Ghost latest:
cd ~/ghost_temp
## Copy the new core directory to your Ghost install:
cp -R core $path_to_ghost_install
## Copy the other key files to your Ghost install directory:
cp index.js *.json $path_to_ghost_install
## Change back to your ghost install directory:
cd $path_to_ghost_install
## Update permissions:
chown -R ghost:ghost *
## Upgrade dependencies:
npm install --production
## Restart Ghost
service $ghost_service start
## if you see that everything is working properly you can remove ghost_temp folder

Steps for laziest admins :P
Save the code (after verification) to a file_name.
Run chmod +x file_name
Run ./file_name
Go sleep

I added that script to my Github account for easier usage:
