The point of the directory? Dotfiles in the cloud. Nuff said.
Yes, I'm trying to keep all of my machines on the same dotfiles, branching my configurations where necessary. This should be a good baseline to build your own dotfiles, if you are just starting out. However, there are definitely configuration options that are particular to me (for example, my Github and IRC usernames, aliases to directories on my box, etc.).
I'm thinking about containing user-specific config in a config file, as soon as I come up with a good way to do that in bash.
If you do want to install:
git clone git@github.com:davejacobs/dotfiles.git
cd dotfiles
bin/install
The install should work on OS X, Arch Linux, and Ubuntu.
If you want your prompt to load faster, consider editing your .bash_profile
and removing completions and language version managers.
