How Do I Revert a Git Repository to a Previous Commit?

Sometimes, you might need to go back to an earlier commit in your Git repository—maybe you introduced a bug, or something just isn’t working as expected. There are a few ways to do this, depending on what you want to achieve.

1. Use git reset (Moves HEAD and Changes History)

If you want to undo commits and keep working from a past point, use:

  git reset --hard 

• This moves the branch pointer back to the specified commit.
  
• --hard deletes all changes after that commit (irreversible).
  
• Use --soft if you want to keep changes staged.
  

2. Use git revert (Keeps History Intact)

If you want to undo a commit without changing history, use:

  git revert 

• This creates a new commit that undoes the changes from the specified commit.
  
• Ideal for shared branches because it doesn’t rewrite history.
  

3. Checkout an Older Commit (For Temporary Changes)

If you just want to test an older version without making permanent changes:

  git checkout 

• This puts you in a detached HEAD state.
  
• To go back, use git checkout main (or your branch name).
  

Which One Should You Use?

• git reset – Best for local changes you want to erase.
  
• git revert – Best for shared repositories where you want to undo but keep history.
  
• git checkout – Best for viewing older commits temporarily.
