An awesome .gitconfig file with some niceties.

.gitconfig

[user]
    name = Your Name
    email = [email protected]
[core]
    autocrlf = input
[color]
    status = auto
    diff = auto
    branch = auto
[alias]
    st = status
    ci = commit
    co = checkout
    cm = commit -m
    br = branch
    hist = log --pretty=format:\"%h %ad | %s%d [%an]\" --graph --date=short
[merge]
    tool = opendiff

Nice list! I wasn't familiar with the color tools at all. Will have to look those up. Here's a few others that I've found handy:

[alias]
    cm = commit -m
    br = branch
    hist = log --pretty=format:\"%h %ad | %s%d [%an]\" --graph --date=short
    type = cat-file -t
    dump = cat-file -p

Awesome thanks, I added a few of them.

I also have:
[alias] ac = !git add -A && git commit

Here is what I have for colors:

[color]
diff = auto
status = auto
branch = 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
[core]
editor = mate -w
