Deploy your site with git

This gist assumes:

• you have a local git repo
• with an online remote repository (github / bitbucket etc)
• and a cloud server (Rackspace cloud / Amazon EC2 etc)
  • your (PHP) scripts are served from /var/www/html/
  • your webpages are executed by apache
• apache's home directory is /var/www/

Linux - "Open any file" via Keyboard Shortcut

Assign this little shell script to a keyboard shortcut Xfce to open a shell -prompt, then have that file / directory opened by it's native program.

Pretty simple, excellent user-experience!

Thanks to Xfce forum member "ToC" who helped me solve a problem with the script

How to install

#!/bin/bash

# This script is no good for servers with multiple-users, I simply
# designed it to quickly push my git tinkerings to my EC2 test server.
# 
# Use at your own risk!
# 
# cd to a local directory under git control and execute this script, it will:
#     create repos on your server
#     modify your local remotes to push to the server

Make sure you have this git alias

git config --global alias.clone-branches '! git branch -a | sed -n "/\/HEAD /d; /\/master$/d; /remotes/p;" | xargs -L1 git checkout -t'

Clone the remote, pull all branches, change the remote, filter your directory, push

git clone git@github.com:user/existing-repo.git new-repo
cd new-repo
git clone-branches

git remote rm origin
