How to config your dotfiles git

Create a directory to hold your git database (the .git dir):

$ mkdir ~/.dotfiles/
$ cd ~/.dotfiles/
~/.dotfiles$ git init

Now we've got a repository set up for our files. It's out of the way of our home directory, so the .git directory won't cause any conflicts with other repositories in your home directory. Here comes the magic part that lets us use this repository to keep our home directory in. Add the dgit alias to your .bashrc or .profile, whichever you prefer:

~/.dotfiles$ echo "alias dgit='git --git-dir ~/.dotfiles/.git --work-tree=\$HOME'" >> ~/.bashrc

​You'll have to log out and in again, or just copy-paste the alias defnition in your current shell. We can now the repository out in our home directory with the dgit command:

~/.dotfiles$ cd ~
$ dgit reset --hard
HEAD is now at 642d86f gitignore

Now the repository is checked out in our home directory, and it's ready to have stuff added to it. The dgit reset --hard command might seem spooky (and I do suggest you make a backup before running it), but since we're ignoring everything, it'll work just fine.

Add files

Everything we do now, we do with the dgit command instead of normal git. In case you forget to use dgit, it simply won't work, so don't worry about that.

A dgit status shows nothing, since we've gitignored everything:

$ dgit status
On branch master
nothing to commit, working directory clean

We add things by overriding the ignore with -f:

$ dgit add -f .profile 
$ dgit commit -m "Added .profile"
[master f437f9f] Added .profile
 1 file changed, 22 insertions(+)
 create mode 100644 .profile

We can push our configuration files to a remote repository:

$ dgit remote add origin your@githublink
$ dgit push origin master
 * [new branch]      master -> master

And easily deploy them to a new machine:

$ git clone your@githublink
$ alias dgit='git --git-dir ~/.dotfiles/.git --work-tree=$HOME'
$ dgit reset --hard
HEAD is now at f437f9f Added .profile
