Learning Git

Git is a software that allows you to keep track of changes made to a project over time. Git works by recording the changes you made to a project, storing those changes, then allowing you to reference them as needed.

  1. A Working Directory where you’ll be doing all the work creating, editing, deleting and organizing files.
  2. A Staging Area where you’ll list changes you make to the working directory.
  3. A Repository where Git permanently stores those changes as different versions of the project.
git init -- creates a new Git repository
git status -- inspects the contents of the working directory and staging area
git add -- adds files from the working directory to the staging area
git diff -- shows the difference between the working directory and the staging area
git commit -- permanently stores file changes from the staging area in the repository
git log -- shows a list of all previous commits
git checkout HEAD filename -- discards changes in the working directory
git reset HEAD filename -- unstages file changes in the staging area
git reset SHA -- can be used to reset to a previous commit in your commit history
git branch -- lists all a Git project’s branches
git branch branch_name -- creates a new branch
git checkout branch_name -- used to switch from one branch to another
git merge branch_name -- used to join file changes from one branch to another
git branch -d branch_name -- deletes the branch specified
git clone -- creates a local copy of a remote
git remote -v -- lists a Git project’s remotes
git fetch -- fetches work from the remote into the local copy
git merge origin/master -- merges origin/master into your local branch
git push origin branch_name -- pushes a local branch to the origin remote
