This is a set of configuration files for a bunch of Unix apps I use regularly.

The way I usually use this is as follows. Change the lines as appropriate for your system.

Install Git:
    $ sudo aptitude install git-core

Change into your home directory and make a clone of the repository:
    $ cd
    $ git clone http://delx.net.au/git/dotfiles .dotfiles

Make a backup of any existing files:
    $ mkdir backup
    $ mv .bash .bash_profile .bashrc .gitconfig .hgrc .inputrc .pythonrc.py .screenrc .terminfo .vim .vimrc backup/

Symlink the config files into your home directory:
    $ ln -sf .dotfiles/{.bash,.bash_profile,.bashrc,.gitconfig,.hgrc,.inputrc,.pythonrc.py,.screenrc,.terminfo,.vim,.vimrc} .
    $ ln -s .dotfiles/.ssh/config .ssh/

Symlink the git hooks
    $ cd .dotfiles && rm -rf hooks && ln -s ../git-hooks hooks

You can add machine specific configs to the bash init scripts by creating files in ~/.bash called environment_local, interactive_local, functions_local, etc
Also, learn how to use Git and use it to version control other config files of yours.
