Create links for all files stored in git to your local dot files. You can now keep backups on git with ease.

git.sh

#!/bin/bash

mkdir -p $HOME/git/dotfiles/vim;

files=("bash_profile bashrc inputrc screenrc vim vimrc zshrc");

for file in $files; do
    if [[ -h $HOME/.$file ]]; then
        unlink $HOME/"."$file;
    elif [[ -e $HOME/.$file ]]; then
        mv $HOME/"."$file $HOME/"."$file"."$(date +%m"."%d"."%Y)
    fi;
    ln -s $HOME/git/dotfiles/$file $HOME/"."$file;
