EBC Exercise 16 git
Embedded Linux Class by Mark A. Yoder
git is a distributed revision control system with an emphasis on being fast. It was initially designed and developed by Linus Torvalds for Linux kernel development. The purpose of this lab is to get hands on experience with git to learn how it works and how to use it.
0. Set Up Git
If you haven't done so already, go to EBC_Exercise_05_Getting_Exercise_Support_Materials#Set_Up_Git and follow the directions for installing and setting up git.
1. Play with git locally
1.1 - About Version Control 1.2 - A Short History of Git 1.3 - Git Basics 1.4 - Installing Git 1.5 - First-Time Git Setup 1.6 - Getting Help 1.7 - Summary
I'll cover Git Basics in class and you have already done parts 1.5 and 1.6 to set up for github. I suggest you take a look at Getting Help and then move on.
2. Git Basics
Chapter is on Git Basics. The topics are:
2.1 - Getting a Git Repository 2.2 - Recording Changes to the Repository 2.3 - Viewing the Commit History 2.4 - Undoing Things 2.5 - Working with Remotes 2.6 - Tagging 2.7 - Tips and Tricks 2.8 - Summary
There is lots of good material here. I suggest you work through it all. Section 2.1 shows how to clone a remote repository.
gitk looks like a nice tool. Be sure to take a look at it.
Questions you should be able to answer after doing chapter 2
- How do you stage a file?
- How do you view staged and unstaged changes?
- How do you view comment history?
- You've just committed something and realize you meant to have committed one more file. How do you add that file to the commit you just did?
- How do you unstage a file?
- How do you unmodify a file?
- After running the
remote -vhow do you tell if a site is read only or read/write?
- What's the difference between a lightweight and an annotated tag?
3. Git Branching
Chapter 3 is on branching. Here's the topics from the book:
3.1 - What a Branch Is 3.2 - Basic Branching and Merging 3.3 - Branch Management 3.4 - Branching Workflows 3.5 - Remote Branches 3.6 - Rebasing 3.7 - Summary
I'll work through 3.1 in class. Read through 3.2 and then do the following exercise.
- clone my repository (The pass phrase is Hiapp)
beagle$ git clone email@example.com:MarkAYoder/gitLearn.git beagle$ cd gitLearn
helloWorld.cand add a
printfwith your name on it.
- Compile to be sure it works.
- stage and commit
helloWorld.c. You may have to merge. Keep everyone else's name in the file.
- Push it to the repository.
Once everyone has done this we should have a file with everyone's name in it.
Moving from svn
Here's a nice article on a common git workflow for those who are moving from svn.
