A little script I use to init git repositories (including those hosted on GitHub and BitBucket). You have to register a push-enabled public key first and it expects a .gitignore and some utility libraries in the same folder.

init.sh

# usage
# init.sh <repository> <folder>

DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null && pwd )"

if [ -d $2/Assets ]; then
  echo "Setting up git repository $1"
else
  echo "An init script for git hosted Unity projects"
  echo "Usage: init.sh <repository> <folder>"
  echo "Please create a Unity project and a git repository first."
  exit
fi


#cp "/Users/pi/Projects/UnityHelpers/.gitignore" .
cp $DIR/.gitignore .
git init
git remote add origin "$1"
git add .gitignore
git commit -m "Initial gitignore commit"
git push -u origin master

echo "Adding folders to $2"
