How do you rename a Git tag?

on

 

To rename a Git tag, you can delete the existing tag and create a new one with the desired name. Here's how you can do it:

Step 1: Delete the Existing Tag:

Use the git tag -d command followed by the existing tag name to delete it. For example, if you want to rename a tag named old-tag:

bash
git tag -d old-tag

Step 2: Create a New Tag with the Desired Name:

After deleting the old tag, you can create a new tag with the desired name using the git tag command. For example, to create a new tag named new-tag at the current commit:

bash
git tag new-tag

Step 3: Push the New Tag to the Remote Repository (Optional):

If you've been working with a remote repository and want to push the new tag to share it with others, you can use the git push command:

bash
git push origin new-tag

In this example, origin is the name of the remote repository, and new-tag is the name of the tag you want to push.

Here's a complete example of renaming a Git tag:

bash
# Step 1: Delete the existing tag
git tag -d old-tag

# Step 2: Create a new tag with the desired name
git tag new-tag

# Step 3: Push the new tag to the remote repository (optional)
git push origin new-tag

After these steps, you will have effectively renamed the Git tag from old-tag to new-tag. Keep in mind that if others have already pulled the old tag, you should communicate the change to them, as they will need to fetch the new tag and delete the old one locally.
