Learn to delete a branch with git branch -d.
Delete a Branch You No Longer Need
When a feature is complete or an experiment is finished, you can delete its branch. The git branch -d command safely deletes a branch whose changes have been merged.
git branch -d old-experimentGit may warn you during a normal deletion if the branch contains changes that have not been merged.
Check Before Deleting
Make sure you are not currently working on the branch you want to delete. Git does not let you delete the active branch; you must switch to another branch first.
git switch main
git branch -d temporary-reportIf you try to delete a branch that has not been merged, the -d operation may be rejected. This warning helps prevent accidental loss of unfinished work.
Practice Safely Delete an Old Branch
Delete the merged branch named completed-feature. Then print a message confirming that the deletion is complete.
