How to Tag a Specific Commit in Git: Simple Guide

To tag a specific commit in Git, use git tag <tagname> <commit-hash>. This creates a tag pointing exactly to the commit you specify by its hash.

Syntax

The basic syntax to tag a specific commit is:

• git tag <tagname> <commit-hash>: Creates a tag named tagname on the commit identified by commit-hash.
• git push origin <tagname>: Pushes the created tag to the remote repository.

Explanation: tagname is your chosen label for the commit, and commit-hash is the unique identifier of the commit you want to tag.

bash

git tag <tagname> <commit-hash>
git push origin <tagname>

Example

This example shows how to tag a specific commit using its hash and then push the tag to the remote repository.

bash

git tag v1.0.0 9fceb02
git push origin v1.0.0

Output

Total 0 (delta 0), reused 0 (delta 0)
To origin
 * [new tag]         v1.0.0 -> v1.0.0

Common Pitfalls

• Using a wrong or incomplete commit hash will cause Git to fail tagging.
• Forgetting to push the tag means it stays only in your local repository.
• Trying to tag a commit without specifying the hash tags the current HEAD by default, which might not be what you want.

Wrong way: git tag v1.0.0 (tags current commit, not specific one)

Right way: git tag v1.0.0 9fceb02

bash

git tag v1.0.0
# tags current commit, not specific one

git tag v1.0.0 9fceb02
# tags specific commit by hash

Quick Reference

Command	Description
git tag	Create a tag on a specific commit
git push origin	Push the tag to remote repository
git show	View details of the tagged commit
git tag -d	Delete a local tag
git push origin :refs/tags/	Delete a remote tag

Key Takeaways

Use git tag <tagname> <commit-hash> to tag a specific commit by its hash.

Always push your tags with git push origin <tagname> to share them remotely.

Verify the commit hash before tagging to avoid mistakes.

If you omit the commit hash, Git tags the current commit (HEAD) by default.

Use git show <tagname> to check which commit a tag points to.
