Git/Tutorial

1. Download & Install Git on your machine

open up your Terminal / Console and type

 git version

if this command is unknown, you have to install git

Mac / Linux: most likely already installed
All other operating systems: git-scm.com

2. Setup

If you're using git for the first time, you might want to setup some configuration settings:

 git config --global user.name "Max Mustermann"
 git config --global user.email max@mustermann.de

These two settings help to identify you when you're pushing your files to a remote server.

Git can produce colorful output with some commands; since some people hate colors way more than the rest likes them, by default the colors are turned off. If you would like to have colors in your output:

 git config --global color.diff auto
 git config --global color.status auto
 git config --global color.branch auto

These settings are global (for your machine), so you only need to do this once.

Adding a Remote git Server

To add a remote git server, type:

git remote add origin ssh://myserver.com

For example, you can use github.com to host your open source projects, or bitBucket.org. You will find an excessive online help on how to setup a remote server on github: How-to-Setup github. Basically, you only need a private/public ssh key and a valid user account.

But remember, you can use git only on your local computer as well, it is not required to have an online server!

Create or select a folder ("myProject") and change the current directory with the bash command cd

cd myProjectPath
git init

Usage

to get the status of your local git repository, query:

git status

to add files you type:

git add myfile.ext

or to add all:

git add *

If you changed something and would like to store these changes as a version, you can "commit" your update:

git commit -a -m "comment about change"

At this point, your commit is only local! You can commit as few or as many changes as you like. But at the end of the day, you should push your changes to the server:

git push origin master

If you are interested in getting the changes from the server to your local machine, type:

git pull

Summary

git version
git init
git remote add origin {ssh://myserver.com} (Add remote Server)
git status
git add .
git commit -a -m "minor changes"
git push origin master (Push to remote Server; where 'master' is the name of your current branch)
