Deleting a local Git tag

What is the output of the command when deleting a local tag named v1.0?

Git

git tag -d v1.0

A Deleted branch 'v1.0' (was 9fceb02)

B error: tag 'v1.0' not found.

C Deleted tag 'v1.0' (was 9fceb02)

D fatal: not a git repository (or any of the parent directories): .git

💡 Hint

Deleting a local tag shows confirmation with the tag name and commit hash.

The command git tag -d v1.0 deletes the local tag and confirms with the tag name and commit hash. If the tag does not exist, it shows an error. Deleting a branch uses a different command.

💻 Command Output

Deleting a remote Git tag

What is the output of the command when deleting a remote tag named release from origin?

Git

git push origin --delete release

A error: unknown option `--delete tag'

B

To origin
 - [deleted]         release

C fatal: remote origin not found.

D Deleted tag 'release' locally

💡 Hint

Deleting a remote tag uses git push origin --delete <tagname> and shows deletion confirmation.

The command deletes the remote tag and confirms with the remote name and deleted tag. Errors occur if the remote is missing or the command syntax is wrong.

❓ Troubleshoot

Why does deleting a remote tag fail?

You run git push origin --delete v2.0 but get the error error: unable to delete 'v2.0': remote ref does not exist. What is the most likely cause?

A The remote 'origin' is not configured.

B You do not have permission to delete tags on the remote.

C The local tag 'v2.0' is missing.

D The tag 'v2.0' does not exist on the remote repository.

💡 Hint

Check if the tag exists on the remote before deleting.

The error means the remote does not have the tag 'v2.0'. Permissions or remote config errors produce different messages. Local tag presence does not affect remote deletion.

Recommended workflow to delete a tag both locally and remotely

Which sequence of commands correctly deletes a tag named hotfix both locally and on the remote named origin?

A git tag -d hotfix && git push origin --delete hotfix

B git tag -d hotfix && git push origin :refs/tags/hotfix

C git push origin --delete hotfix && git tag -d hotfix

D git push origin :refs/tags/hotfix && git tag -d hotfix

💡 Hint

Delete local tag first, then delete remote tag with --delete option.

The recommended way is to delete the local tag first with 'git tag -d' then delete the remote tag with 'git push origin --delete hotfix'. Using refspec syntax is less clear.

Understanding the effect of deleting tags on collaborators

After deleting a remote tag v3.0 with git push origin --delete v3.0, what must collaborators do to remove the tag from their local repositories?

A Run <code>git fetch --prune origin</code> to update and remove deleted remote tags locally.

B Run <code>git tag -d v3.0</code> only; no fetch needed.

C Run <code>git pull</code> to automatically delete the tag locally.

D No action needed; tags are deleted automatically on fetch.

💡 Hint

Local tags are not deleted automatically; pruning is required.

Deleting a remote tag does not remove it from local clones automatically. Collaborators must prune remote-tracking tags with 'git fetch --prune origin' and delete local tags manually if needed.
