To delete a Git branch both locally and remotely, follow these steps:

1. Delete a Local Branch

Run the following command to delete a local branch:

git branch -d <branch_name>

• Use -d for a safe deletion, which will only delete the branch if it has been fully merged.
• Use -D if you want to force delete the branch, even if it hasn’t been merged.

Example:

git branch -d my-feature-branch

If the branch hasn't been merged, force delete it with:

git branch -D my-feature-branch

2. Delete a Remote Branch

Run the following command to delete a branch from the remote repository:

git push origin --delete <branch_name>

Example:

git push origin --delete my-feature-branch

This will remove the branch from the remote (e.g., GitHub, GitLab).
