How can I rollback a git repository to a specific commit?

Rolling back a Git repository to a specific commit is a common task when you need to undo changes or return to a stable state. But how exactly can you achieve this, and what commands are safest to use?

1. Using git reset

• git reset moves the current branch pointer to a specific commit.
  

Example:

   git reset --hard 

• The --hard option resets the working directory and staging area to match the commit.
  
• Warning: This removes all changes after the specified commit, so use it carefully, especially if changes are pushed to a shared repository.
  

2. Using git checkout for Detached HEAD

• You can temporarily check out a specific commit without changing the branch.
  

Example:

   git checkout 

This puts you in a detached HEAD state, useful for inspecting past code or testing, but not recommended for long-term work.

3. Using git revert

• Unlike reset, git revert creates a new commit that undoes changes introduced by a specific commit.
  

Example:

   git revert 

This is safer for shared repositories because history is preserved.

Key Points to Remember:

• Use git reset for local rollbacks or rewriting history before pushing.
  
• Use git revert to safely undo changes on public/shared branches.
  
• Always backup or stash your changes before performing a rollback to avoid losing work.
  

In summary, rolling back to a specific Git commit can be done using reset, checkout, or revert depending on whether you want to modify history or safely undo changes. Choosing the right method ensures your workflow stays safe and controlled.
