How to Commit and Push a Branch in Git

What is a Git Branch?

A branch in Git is a lightweight movable pointer to a commit. It represents an independent line of development, allowing you to work on features or fixes without affecting the main codebase until you're ready to merge your changes.

Check your current branch and status

git branch        # Shows all local branches with current branch marked with *
git status        # Shows modified files and staging status

Stage all changes

git add .         # Stages all changes in the current directory and subdirectories
git add -A        # Stages all changes (including deletions) in the entire repository

Commit your changes

git commit -m "Your descriptive commit message here"

You can also stage and commit in one step (only for tracked files):

git commit -am "Your descriptive commit message here"

Push your branch to the remote repository

If the branch already exists on the remote:

git push         # Pushes current branch to its upstream remote

If this is a new branch that doesn't exist on the remote yet:

git push -u origin your-branch-name   # Creates remote branch and sets upstream

Replace your-branch-name with the name of your current branch.

Additional Useful Git Commands

Branch Management

git checkout -b new-branch-name       # Create and switch to a new branch
git checkout existing-branch          # Switch to an existing branch
git branch -d branch-name             # Delete a branch locally
git push origin --delete branch-name  # Delete a branch on the remote

Syncing with Remote

git fetch                             # Download objects and refs from remote
git pull                              # Fetch and integrate changes from remote
git merge origin/branch-name          # Merge a remote branch into your current branch

Viewing History

git log                               # View commit history
git log --oneline                     # View simplified commit history
git diff                              # View unstaged changes
git diff --staged                     # View staged changes

Best Practices

1. Pull before pushing: Always git pull before pushing to avoid conflicts.
2. Commit frequently: Make small, focused commits with clear messages.
3. Use descriptive branch names: Name branches according to what they contain (e.g., feature/user-authentication, bugfix/login-error).
4. Keep branches up to date: Regularly merge or rebase with the main branch.
5. Delete merged branches: Clean up branches after they've been merged.
6. Review changes before committing: Use git status and git diff to review changes.
