Git Quick Start
Git is...
Git is a free & open source, distributed version control system designed to handle everything from small to very large projects with speed and efficiency.
Every Git clone is a full-fledged repository with complete history and full revision tracking capabilities, not dependent on network access or a central server.Branching and merging are fast and easy to do.
Git is used for version control of files, much like tools such as
Mercurial, Bazaar,
Subversion, CVS,
Perforce, and
Team Foundation Server.
Creating and Commiting
$ cd (project-directory)
$ git init
$ (add some files)
$ git add .
$ git commit -m 'Initial commit'
$ git clone git://github.com/git/hello-world.git
$ cd hello-world
$ (edit files)
$ git add (files)
$ git commit -m 'Explain what I changed'
$ git format-patch origin/master
Basic Commands
$ git status
$ git log
The basic Git workflow goes something like this:
1. You modify files in your working directory.
2. You stage the files, adding snapshots of them to your staging area.
3. You do a commit, which takes the files as they are in the staging area and stores that snapshot permanently to your Git directory.
