How to revert to a previous version of the project?

 
Step 1: Open Your Terminal or Command Prompt
 

Open the terminal (Linux/macOS) or Git Bash/Command Prompt (Windows) so you can run Git commands.

 
Step 2: Navigate to Your Local Repository
 

Use the cd command to move into the folder where your project is stored.

cd path/to/your/project

 
Step 3: View the Commit History
 

Run git log in a concise form to find the commit hash you want to revert to.

• The hash is the series of characters at the start of each line.
• You’ll use that hash in the next step.

git log --oneline

 
Step 4: Check Out the Desired Commit Locally
 

This lets you inspect the project at that point in time without altering your current branch permanently.

git checkout COMMIT\_HASH

Replace COMMIT_HASH with the actual identifier (for example, a1b2c3d).

 
Step 5: Create a New Branch from the Old Commit (Optional but Safe)
 

If you want to preserve your current work, create a new branch at that commit first.

• This branch will hold the reverted state.

git checkout -b revert-to-old-version

 
Step 6: Hard Reset Your Main Branch to That Commit
 

If you prefer to move your existing branch (for example, main) back in time, switch back to it and reset it.

• WARNING: A hard reset rewrites commit history and can discard uncommitted changes.

git checkout main
git reset --hard COMMIT\_HASH

 
Step 7: Push the Reverted State to GitHub
 

After resetting, update the remote branch. If you reset the main branch, you must force-push.

git push origin main --force

• Force-pushing rewrites history on GitHub. Coordinate with your team first.

 
Step 8: Alternative Method—Use git revert to Create a New “Undo” Commit
 

Instead of rewriting history, you can generate a new commit that reverses one or more earlier commits. This is safer for shared branches.

git checkout main
git revert COMMIT\_HASH
git push origin main

• This will prompt you to confirm the commit message; save and close to complete.
• Multiple commits can be reverted in a single command by listing hashes.

 
Step 9: Verify the Reverted Version on GitHub
 

Go to your repository on GitHub and confirm that the files and commit history reflect the previous version you intended.
