Git is a free and open source distributed tracking system git-scm.com. It is a powerful source-control tool with powerful multi-user features. The ease of creating and working with multiple branches enables the "Pull-Request" model of development used on GitHub and several other Git-based hosting sites.
If you are developing code as part of your job or as a student doing reasearch, you should take the time to learn a little bit about Git. This page is here to provide a few tips that the MOOSE team has learned over the years. It is not meant as a beginners tutorial.

Downloading a single PR from Github
If you want to try out somebody elses code, you can always add a new remote to pull in their repository. If you do this a lot however, you might find yourself with a huge number of remotes that you don't really care about. There is a better way: https://help.github.com/articles/checking-out-pull-requests-locally/
To enable bash completion for git (so you can tab-complete 'git co' or 'git br' commands) download git_completion.sh to your home directory, and append the following line to the end of your ~/.bash_profile (or ~/.bashrc)
If you would like to have the name of the current branch in your prompt, download git_prompt.sh to your home directory, and append the following lines to the end of your ~/.bash_profile (or ~/.bashrc)
source ~/git_prompt.sh export PS1='$(__git_ps1 "(%s)")$ '
Assuming your prompt is just '$ ', adding this line to your
.bash_profile will cause it to look like
(master)$ whenever you
cd into a directory containing a git repo in where the
master branch is checked out.
The first time you try to commit to git a new machine, it'll likely complain that it doesn't know who you are and will tell you to set your name and email address. Once you run those commands a hidden file will be created in your home directory called
.gitconfig. This file can be customized to make using git easier once you learn your way around. As a start, you might try to shorten up some of the longer commands so that you don't have to type them all the time. You might also turn on more color, especially if you work on the command line all day. Here are a few suggestions to get you started. There are many more options that can be added git-config.
[user] name = <Your Name> email = <Your Email Address> [color] diff = auto status = auto branch = auto interactive = auto ui = true pager = true [alias] co = checkout di = diff st = status ci = commit stat = status br = branch
