Configure your identity within Git globally or on a per-repository basis to accurately track your contributions

2. Initialize Git Repositories:

Start version controlling your projects by initializing Git repositories.

$ git init

3. Add Project Files:

Add files to the staging area in preparation for committing changes.

$ git add file
$ git add *.php

4. Verify Added Files:

Check the status of your files to see which ones are staged for commit.

$ git status

5. Commit Changes to the Repository:

Record changes to the repository along with a descriptive message.

$ git commit
$ git commit -m "First Commit"

6. Display the Logs:

View commit history to track changes and understand project evolution.

$ git log
$ git log --file

7. Verify Project Branches:

List existing branches in your repository to navigate between different versions.

$ git branch

8. Reset Project Branches:

Reset branches to a previous state, undoing commits and changes as needed.

$ git reset
$ git reset --soft
$ git reset --hard

9. Add a New Branch:

Create a new branch to isolate development efforts or work on a specific feature.

$ git branch new-feature

10. Switch between Branches:

Switch between branches to access different versions of your project.

$ git checkout new-feature

11. Delete a Project Branch:

Remove unnecessary branches once they have served their purpose.

$ git checkout master
$ git branch -D new-feature

12. Check Differences among Commits, Trees, and Files:

Analyze differences between commits, trees, and individual files to understand changes.

$ git diff
$ git diff new-feature master

13. Merge Two Branches:

Combine changes from one branch into another to integrate new features or bug fixes.

$ git merge fixes new-feature
$ git merge -s ours obsolete
$ git merge --no-commit main

14. Revert Existing Commits:

Undo changes introduced by previous commits without altering commit history.

$ git revert ad9ef37d88ad4gfyg90aa6a23f71e77
$ git revert HEAD~3

15. Stash Working Directory:

Temporarily store changes that are not ready to be committed.

$ git stash
$ git stash list

16. Clone a Repository:

Duplicate an existing repository to your local machine for collaboration.

$ git clone
$ git clone git://example.com/git.git/ test-dir

17. Pull New Updates:

Fetch and merge changes from a remote repository into your local branch.

$ git pull

18. Push Your Updates:

Upload your local commits to a remote repository to share your work.

$ git push

19. Display Remote Repositories:

List remote repositories associated with your local repository.

$ git remote
$ git remote --verbose

20. Connect to Remote Repositories:

Establish connections to remote repositories for collaboration.

$ git remote add origin

21. Add Tags to Your Project:

Tag specific commits to mark significant milestones or releases.

$ git tag 1.0.0
$ git push origin --tags

22. Fetch Remote Data:

Download objects and refs from another repository to keep your local copy up to date.

$ git fetch origin

23. Restore Non-Committed Changes:

Revert changes made to files that have not been staged or committed.

$ git restore --staged test.php
$ git restore --source=HEAD --staged --worktree test.php

24. Remove Files:

Delete files from the working directory and stage the removal for the next commit.

$ git rm *.php
$ git rm -r dir/
$ git rm --cached *.php

25. Move or Rename Files:

Change the name or location of files within your project while preserving their history.

$ git mv test.py new-test.py
$ mv test.py new-test.py
$ git add new-test.py
$ rm test.py

26. Clean Untracked Files:

Remove untracked files from your working directory to keep it clean and organized.

$ git clean
$ git clean -n

27. Optimize Local Repositories:

Optimize the local repository’s database to improve performance and reduce disk usage.

$ git gc

28. Archive Local Repositories:

Create a compressed archive of the repository for sharing or backup purposes.

$ git archive --output=test --format=tar master

29. Search for Patterns:

Search for specific text patterns within the repository’s contents.

$ git grep -iw 'import' master
$ git grep 'import' $(git rev-list --all)

30. Manage Working Trees:

Create, list, add, and remove linked working trees to your repository.

$ git worktree list
$ git worktree add new-branch
$ git worktree remove new-branch
$ git worktree prune

31. Prune Untracked Objects:

Remove unreachable objects from the repository to reclaim disk space.

$ git prune --dry-run
$ git prune --verbose --progress

32. Pack Unpacked Objects:

Compress loose objects in the repository into pack files to save space and improve performance.

$ git repack

33. List Unpacked Objects:

Display statistics about the repository’s object storage.

$ git count-objects

34. Validate the Object Database:

Check the integrity of the repository’s object database to ensure it is not corrupted.

$ git fsck
