Lest see the important github commands.

• Top Git Commands :-

1. git init: Initializes a new Git repository in the current directory. This command creates a hidden directory named `.git`, which contains all the necessary metadata for version control.

2. git clone [url]: Clones a repository from a specified URL into a new directory on your local machine. This command sets up all the necessary connections to the remote repository for fetching and pushing changes.

3. git add [file]: Adds changes in a specific file or all changed files in the working directory to the staging area. Files in the staging area are ready to be included in the next commit.

4. git commit -m "[message]": Records changes to the repository with a descriptive commit message. Commits represent snapshots of your project at specific points in time, making it easy to track changes and collaborate with others.

5. git push: Uploads local repository content to a remote repository, making your changes accessible to others and synchronizing your local branch with its remote counterpart.

6. git pull: Fetches changes from the remote repository and merges them into the current local branch. This command is used to update your local repository with changes made by others.

7. git status: Displays the current status of the working directory and staging area. It shows which files are modified, staged, or untracked, providing a summary of the repository's state.

8. git branch: Lists all local branches in the current repository. Branches allow for parallel development and isolation of changes, making it easier to work on multiple features or fixes simultaneously.

9. git checkout [branch]: Switches to the specified branch, updating the working directory to reflect the selected branch's state. This command is also used to create new branches with the `-b` flag.

10. git merge [branch]: Integrates the specified branch's history into the current branch, combining changes and resolving any conflicts that may arise during the merge process.

11. git remote -v: Lists the remote repositories along with their URLs. Remotes are references to repositories hosted elsewhere (e.g., GitHub, GitLab), enabling collaboration and synchronization.

12. git log: Displays commit logs, showing the commit history, authors, dates, and commit messages. This command helps track changes and understand the project's development timeline.

13. git reset [file]: Unstages the specified file while preserving its contents, allowing you to undo staging changes before committing.

14. git rm [file]: Deletes the specified file from the working directory and stages the deletion. This command removes tracked files from version control.

15. git stash: Temporarily shelves changes that haven't been committed, allowing you to switch branches or work on other tasks without committing incomplete work.

16. git tag [tagname]: Creates a lightweight tag pointing to the current commit, providing a convenient way to mark specific commits (e.g., releases, milestones).

17. git fetch [remote]: Downloads objects and refs from another repository, updating your local references without merging any changes into your branches.

18. git merge --abort: Aborts the current conflict resolution process, reverting the repository to its pre-merge state and canceling the merge operation.

19. git rebase [branch]: Reapplies commits from the specified branch on top of another base tip, integrating changes from one branch onto another cleanly and maintaining a linear commit history.

20. git config --global user.name "[name]" and git config --global user.email "[email]": Sets the name and email to be used with your commits, associating your identity with the Git repository.

21. git diff: Shows changes between commits, commit and working tree, or any two commit trees, helping to visualize and understand differences in code and file content.

22. git remote add [name] [url]: Adds a new remote repository with the specified name and URL, enabling you to fetch and push changes to multiple remote locations.

23. git remote remove [name]: Removes the specified remote repository from the list of remotes, disconnecting your local repository from that remote location.

24. git checkout -b [branch]: Creates a new branch with the specified name and switches to it, allowing for seamless branch creation and checkout in a single command.

25. git branch -d [branch]: Deletes the specified branch from the local repository, removing its commit history and changes. Use `-D` instead of `-d` to force deletion without checking for merged changes.

26. git push --tags: Pushes all tags from the local repository to the remote repository, ensuring that tagged commits are available to other collaborators and for deployment.

27. git cherry-pick [commit]: Picks a commit from another branch and applies it to the current branch, allowing you to include specific changes from one branch into another.

28. git fetch --prune: Prunes remote tracking branches that no longer exist on the remote repository, keeping your local tracking branches up-to-date and removing obsolete references.

29. git clean -df: Removes untracked files and directories from the working directory, helping to keep the repository clean and removing unwanted artifacts.

30. git submodule update --init --recursive: Initializes and updates submodules recursively, ensuring that submodules are properly initialized and updated to their specified revisions.


Some Advance Git Commands :-

31. git commit --amend: Modifies the last commit with new changes or an updated commit message. Useful for making quick corrections or additions to the latest commit.

32. git log --oneline: Displays a condensed version of the commit history, showing each commit on a single line with abbreviated commit hashes and commit messages.

33. git blame [file]: Shows the revision and author of each line in a file, helping to track changes and understand who modified specific code sections.

34. git branch -m [old_branch_name] [new_branch_name]: Renames a local branch from the old name to the new name, maintaining its commit history and associated changes.

35. git checkout -- [file]: Discards changes in a specific file and reverts it to the last committed version, helpful for undoing local modifications.

36. git remote show [remote]: Displays detailed information about a specific remote repository, including fetch and push URLs, tracked branches, and more.

37. git revert [commit]: Creates a new commit that undoes the changes introduced by a specific commit, effectively reversing its effects in the commit history.

38. git reflog: Shows a log of all Git actions performed in the repository, including commits, merges, branch operations, and resets, providing a detailed history of repository activity.

39. git tag -a [tagname] -m "[message]": Creates an annotated tag with a message at the current commit, providing additional context or information about the tagged commit.

40. git remote update: Fetches the latest changes from all remote repositories and updates the local tracking branches, ensuring your repository is synchronized with remote changes.

41. git bisect: Helps find the commit that introduced a bug by performing a binary search through the commit history, allowing you to identify the problematic commit systematically.

42. git stash pop: Removes and applies the most recent stash from the stash stack, restoring the changes to the working directory that were previously stashed.

43. git clean -n: Performs a dry run of the `git clean` command, showing which untracked files and directories would be deleted without actually deleting them.

44. git log --graph: Displays a textual representation of the commit history graph, showing branch merges, divergences, and commit relationships in a more visual format.

45. git cherry-pick --no-commit [commit]: Picks a commit from another branch but does not automatically create a new commit, allowing you to modify or review changes before committing.

46. git remote rename [old_name] [new_name]: Renames a remote repository reference in your local repository from the old name to the new name, updating remote tracking configurations.

47. git tag -l "[pattern]": Lists tags matching the specified pattern, useful for finding and filtering tags based on naming conventions or search criteria.

48. git diff --cached: Shows the changes between the staging area (index) and the last commit, helping to review staged changes before committing them.

49. git show [commit]: Displays detailed information about a specific commit, including commit metadata, changes introduced, and the commit message.

50. git push [remote] --force: Forces the push of local commits to a remote repository, overwriting its history with the local branch's history. Caution: Use with care as it can overwrite others' changes.
