These are config files to set up a system the way I like it.

git clone git://github.com/sognat/.dot ~/.dot
ln -s ~/.dot/gitignore ~/.gitignore
ln -s ~/.dot/vim ~/.vim
ln -s ~/.dot/vim/vimrc ./.vimrc
ln -s ~/.dot/zsh ~/.zsh
ln -s ~/.dot/zsh/zshrc ~/.zshrc

I am running on Mac OS X Terminal with zsh shell. If you like to switch from old bash, use the following command.

chsh -s /bin/zsh
