Important git commands everyone needs to know.🎯

1. Basic Git Commands:

• Clone a repository:
  git clone <GitHub-link>

• Add a file to staging:
  git add <file-name>

• Add all changes to staging:
  git add .

• Commit changes with a message:
  git commit -m "<message>"

• Push changes to the main branch:
  git push origin main

---

2. Initialize a Repository:

• Create a new repo locally:
  git init

• Connect to a remote repository:
  git remote add origin <link>

• Verify the remote connection:
  git remote -v

• Check current branch:
  git branch

• Rename branch to "main":
  git branch -M main

• Push changes to "main":
  git push origin main

---

3. Branch Commands:

• Check current branch:
  git branch

• Rename branch to "main":
  git branch -M main

• Switch to another branch:
  git checkout <branch-name>

• Create and switch to a new branch:
  git checkout -b <new-branch-name>

• Delete a branch:
  git branch -d <branch-name>

---

4. Merging Code:

Way 1:

• Compare branches/files:
  git diff <branch-name>

• Merge branches:
  git merge <branch-name>

Way 2:

• Create a Pull Request (PR):
  Use GitHub to review and merge changes.

• Pull latest changes from the remote:
  git pull origin main

---

5. Resolving Merge Conflicts:

This happens when Git can't automatically combine code. You'll need to review and fix the conflicting parts manually.

---

6. Undoing Changes:

Case 1: Undo staged changes

• Reset specific files: git reset <file-name>

• Reset all staged changes: git reset

Case 2: Undo last commit:

• Undo one commit: git reset HEAD~1

Case 3: Undo multiple commits:

• Reset to a specific commit: git reset <commit-hash>

• Hard reset (delete all changes after a commit): git reset --hard <commit-hash>

---

7. Fork:

A fork is a copy of someone else’s repository. You can use it to make changes independently. It shares the original repo's code and settings.
Fork is a rough copy.
