Introduction to git - a powerful version control system

block structure

  • Why git?
    • 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
    • problems that occurred
    • conclusion

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

installation on ubuntu

We will use the version from the git ppa:

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
    • 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

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
