To delete a branch with Git, you can use the git branch command with the -d option, followed by the name of the branch you want to delete. Here's an example:

```bash
git branch -d branch_name
```

This will delete the branch named branch_name if it has been fully merged into the current branch. If the branch has not been merged, Git will give you an error message to prevent you from losing any work.

If you want to force the deletion of a branch that has not been merged, you can use the -D option instead:

```bash
git branch -D branch_name
```

This will delete the branch named branch_name even if it has unmerged changes. However, be careful when using this option, as you could lose any uncommitted changes that were made on the branch.
