Study Notes
Git and GitHub Overview
- Git is a distributed version control system for tracking code changes.
- A local repository contains the entire project history, enabling efficient branching and merging.
- GitHub is a cloud-based Git repository hosting service.
- Other popular options include GitLab, Bitbucket, and SourceForge.
- GitHub provides additional features like access control, wikis, and issue boards.
Initializing Repositories
- Initialize a local repository using
git initin the desired directory.- Creates a hidden
.gitdirectory containing repository information.
- Creates a hidden
- Configure Git with your name and email using
git config:-
git config --global user.name "Your Name" -
git config --global user.email "[email protected]"
-
- Add your email address on GitHub to attribute commits to your profile and contributions graph.
Working Directory and Staging Area
- Working Directory: Stores untracked and modified files since the last commit.
- Check status with
git status.
- Check status with
- Staging Area: Holds changes ready for commit.
- Add specific files to staging area with
git add <filename>. - Add all changes with
git add ..
- Add specific files to staging area with
Committing Locally
- Commit changes from the staging area using
git commit -m "Your Commit Message". - Use commit messages to explain changes made.
- Optionally, specify files to commit with
git commit <filename> -m "..."for specific files.
Pushing to Remote
-
git push: Uploads local changes to a remote repository. - Conventionally, the remote branch name mirrors the local branch.
-
originis a common remote alias.
-
Git Branching
-
masterbranch: Holds production-ready code. - Branches are timelines of project updates, created through snapshots of the parent branch.
- Create a new local branch with
git branch <branch-name>. - Switch to another branch with
git checkout <branch-name>. - Create and switch at once with
git checkout -b <branch-name>. - Merge changes from one branch to another:
-
git merge <branch-name>(on the target branch) - from command line. - Usually involves a pull request to merge on GitHub rather than using
git mergelocally.
-
Working with Remote Repositories (Command Line)
-
git clone <remote-repo-address>: Clones a remote repository locally. -
git remote add <alias> <remote-repo-address>: Adds a remote repo manually;origincommon. -
git remote -v: Lists connected remote repositories. -
git fetch <remote> <branch>: Downloads changes from the remote; does not commit. -
git pull <remote> <branch>: Fetches and merges remote changes to local. Avoids conflicts. - Git pull without arguments defaults to fetching the repository/branch.
Pull Requests (GitHub)
- Create pull requests to merge branches on GitHub.
- Choose the source and target branch using the "compare" and "base" dropdowns.
- Click on "Create pull request".
- Merge the changes after review.
Commit Workflow Recipe
- Stage changes (
git add .). - Commit staged changes (
git commit -m "Message"). - Pull down remote changes to your own (
git pull). - Push your local changes now. (
git push).
