# Introduction to git - a powerful version control system
## block structure

- poll from registration
- other points from our list
- git installation hands on
- git on the command line
- navigate manipulate on cli
- ls, pwd, cd, mv, rm, cp, mkdir, rmdir
- short break (optional)
- (like) try git on beamer (closed laptops)
- try git would be 1.1 to 1.9
- init
- status
- add
- commit
- log (metadata only)
- short break (optional)
- hands on - created project
- multiple commits
- multiple files
- diff
- log (with patch)
- wrap up hands on

## Why git?
### Why would you want to use a VCS, e.g. git?
- Summary of answers to question from registration.
- git helps you to keep an overview of a project.
### Thoughts from the net “Have you ever:”
- Made a change to code, realised it was a mistake and wanted to revert back?
- Lost code or had a backup that was too old?
- Had to maintain multiple versions of a product?
- Wanted to see the difference between two (or more) versions of your code?
- Wanted to prove that a particular change broke or fixed a piece of code?
- Wanted to review the history of some code?
- Wanted to submit a change to someone else's code?
- Wanted to share your code, or let other people work on your code?
- Wanted to see how much work is being done, and where, when and by whom?
- Wanted to experiment with a new feature without interfering with working code?
In these cases, and no doubt others, a version control system should make your life easier.
To misquote a friend: A civilised tool for a civilised age.

## git installation hands on
[instructions](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
### installation on ubuntu
We will use the version from the git ppa:
```bash
sudo apt-get install ppa-purge
sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install git
```
### installation on windows
- [Download](https://git-scm.com/download/win)
- choose 64 bit
- portable if you do not have admin rights
- default install options look OK
- Git Bash
- Windows Explorer context menue has *Git Bash Here* and *Git GUI Here* options
- Windows credential window will pop up when accessing remotes with authentication
### navigate and manipulate on cli
- pwd
- ls
- cd
- mv
- rm
- cp
- mkdir
- rmdir
### configure git
```bash
git config --global user.name "Your Name"
git config --global user.email "your.name@idiv.de"
```
- eventually additionally configuration for windows/linux/mac stuff
- line break configuration done during install for windows
- eventually mention difference global local
## short break (optional)
## show try git like tutorial on beamer (closed laptops)
- try git would be 1.1 to 1.9
- create project directory
- init
- status
- add
- commit
- log (metadata only)
## short break (optional)
## hands on - created project
- multiple commits
- multiple files
- diff
- log (with patch)
- test this with a windows and mac machine to see things like editor, linebreaks, etc.
## wrap up hands on
- problems that occurred
- conclusion
