(soon for windows, too.)
Configure things:
git config --global user.name "Your Name"
git config --global user.email "[email protected]"
git config --global alias.co checkout
git config --global apply.whitespace nowarn
Setup an RSA SSH key
ssh-keygen -t rsa
The prompt will ask you for a name. Keep it default if you are not that experienced with git. -- leave password blank if you want to. Otherwise you have to enter it with every push if you don't configer it otherwise.
cat ~/.ssh/id_rsa.pub | pbcopy
Paste that code into your settings page on your repository host(s).
Get happy Git colors. Paste the following into your ~/.gitconfig file:
[color]
branch = auto
diff = auto
status = auto
[color "branch"]
current = yellow reverse
local = yellow
remote = green
[color "diff"]
meta = yellow bold
frag = magenta bold
old = red bold
new = green bold
[color "status"]
added = yellow
changed = green
untracked = cyan
Create a ~/.gitexcludes file and paste in this:
.DS_Store
There, now you don't have to ignore that every time.
Add the following to your ~/.bash_profile or ~/.bashrc:
*deprecated*
source /usr/local/git/contrib/completion/git-completion.bash
GIT_PS1_SHOWDIRTYSTATE=true
export PS1='[\u@mbp \w$(__git_ps1)]\$ '
On Mavericks 10.9 GIT has moved into XCodes App folder. (Thanks to mastbaum) So use this code instead:
source /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-completion.bash
source /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-prompt.sh
GIT_PS1_SHOWDIRTYSTATE=true
export PS1='\u@\h:\w$(__git_ps1)$ '
Also if you did install git with the help of homebrew you have to change the path above to something like this (have a look at your homebrew folder nonetheless to be sure):
source /usr/local/etc/bash_completion.d/git-completion.bash
That will add tab auto-completion for Git branches, display the current branch on your prompt, and show a '*' after the branch name if there are unstaged changes in the repository, and a '+' if there are staged (but uncommitted) changes. It will look something like this in your terminal:
[user@computer ~/Sites/example.com (master*)]$
If you want to have a different email address for a particular project (a personal project on your work computer, perhaps?), just run this command inside that project's folder:
git config user.email "[email protected]"
It's the same command as before, this time just omitting the --global.
I will update this with some new information and tipps from time to time. This is used for my work at Furtwangen University as well as in my position as a student at Furtwangen University and in some group projects as a knowledge base.
