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
