Exercises

Understanding git concepts

Try and explain:

• Why do we use Git at all?
• What is the "workspace"?
• What is the "index" or "staging area"?
• What is the "stash"?
• What is the difference between a local and a remote repository?
• What is a "Fast Forward"?

Play around on code.makandra.de

• In an earlier lesson we build a searchable address book. Create a repository for that program in your personal namespace (/firstname.lastname).
• Add and commit the files
• Create a branch and make some small changes there
• Push changes to the server
• Make a merge request from the branch to your master
• Accept the merge request

Play around on github.com

• Sign up
• Create a repository in your personal namespace (/username)
• Add some files, push them
• Delete the repository when done

Important

We have some rules for using private GitHub accounts on your work PC.
