Initialize a git repository and copy a git ignore file from your home directory

initgit.sh

# Copy this file to /usr/local/bin/ on your Mac
# type chmod +x initgit.sh
# From now on, on any folder, you can just type initgit.sh and a new git repo with a default .gitignore file will be created for you.

#! /bin/sh

git init
cp ~/.gitignore .
rm -r build/
git add .gitignore
git add *
git commit -a -m "Initial Commit"
