git status             # Shows the current status of changes (staged, unstaged, untracked).

📦 Commit History & Undo

git commit -m "message"                    # Commits all staged changes with a message.

git log                                  # Shows the list of past commits.

git reset <commit_id>         # Uncommits all commits after the specified commit.
                              # Use the commit ID from git log.

📦 Pushing Code

git push origin main           # Pushes to remote named origin, branch main.

---

📦 Stash Commands

git stash               # Saves all staged and unstaged changes, and cleans working directory.
                        # Keeps local changes safe without committing.

git stash pop            # Applies the latest stashed changes back to working directory.

git stash clear           # Deletes all stashed entries (irreversible).

REMOTE REPO :

git remote add origin url                # Naming your remote repo as origin with url
git remote -v                            # List all URLs saved

git branch                               # Show current branch
git branch feature                       # Create new branch called feature
git checkout feature                     # Shift to feature branch

WORKING WITH EXISTING PROJECTS :

i)

1. Fork ur desired repo to ur account.

2. git clone < forked_repo_url >

3. Make ur changes and while working:

4. Never push on main branch, create on newly created branch only.

5. Every time u are going to push, create a new branch for every pr.

ii)

1) Just like removing commits above i-th commit with git reset id-of-commit, similarly u can remove prs by u above i-th pr by simply git reset id-of-commit, and then do git push origin raj -f where raj is branch u previously pushed those extra prs

[ useful while ur pushing many prs on a same branch in ur remote repo. ]

2) How to sync upstream repo and ur [ remote repo, local repo ] ??

git checkout main

git pull upstream main [ Now both upstream and local repos synced]

git push origin main [ Now ur remote repo also synced]
