How can I recover a deleted Git branch?

I accidentally deleted a Git branch. How can I recover it?

You can recover a deleted Git branch using the command git reflog to find the commit hash and then create a new branch from it.

What if I don't see the branch in the reflog?

If the branch isn't in the reflog, it might be permanently lost unless you have a backup or the commit hash from another source.

Is there a way to prevent this from happening in the future?

Yes, you can use git branch -m to rename branches instead of deleting them, or create backups before making significant changes.

Can I recover a branch that was deleted a long time ago?

If the commits are still in the reflog, you can recover them. However, if the reflog has expired, it may be difficult to retrieve.
