Tracking changes with a local repository
|
git init initializes a new repository
git status shows the status of a repository
Files can be stored in a project’s working directory (which users see), the staging area (where the next commit is being built up) and the local repository (where commits are permanently recorded)
git add puts files in the staging area
git commit saves the staged content as a new commit in the local repository
Always write a log message when committing changes

Looking at history and differences
|
git log shows the commit history
git diff displays differences between commits
git checkout recovers old versions of files
|
|
Branching
|
git branch creates a new branch
Use feature branches for new ideas and fixes, before merging into master
merging does not delete any branches
