要強(qiáng)制刪除未合并的Git分支，可使用git branch -D <branch-name>命令。該命令會(huì)忽略分支的合并狀態(tài)直接刪除它，適用于測(cè)試后無(wú)用的分支、被放棄的功能分支或需從遠(yuǎn)程重新創(chuàng)建的本地舊分支等情況。但需注意：刪除后提交記錄仍短暫存在于本地，最終會(huì)被垃圾回收機(jī)制清理；誤刪后可通過(guò)git reflog恢復(fù)，但窗口期較短。因此，執(zhí)行前務(wù)必確認(rèn)分支無(wú)用、無(wú)人協(xié)作且名稱正確，避免數(shù)據(jù)丟失。

Sometimes you need to delete a Git branch that hasn’t been merged, and Git might stop you with a warning. If you're sure you want to force delete it anyway, there’s a simple way to do that.

Use the -D flag to force delete a branch

Git normally stops you from deleting a branch that hasn't been merged to prevent accidental data loss. But if you're certain you don't need that branch anymore, you can override this safety check by using the -D option:

git branch -D <branch-name>

This command will delete the branch regardless of its merge status. Just make sure you really don’t need any commits from that branch before running it — once it's gone, recovering it could be difficult unless you know the exact commit hash.

What happens when you force delete a branch?

When you delete a branch with -D, Git doesn’t actually remove the commits right away — they’re still in your local repository for a while (thanks to Git’s reflog), but they become unreachable. Eventually, Git’s garbage collection will clean them up.

So, if you accidentally delete a branch, you may still be able to recover it using:

• git reflog to find the last commit on that branch
• Then creating a new branch pointing to that commit

But this only works for a short time and only on your local repo. So again — be careful when using -D.

When should you actually use force delete?

Here are some real-world cases where force-deleting a branch makes sense:

• You created a test branch, tried something out, and decided not to keep the changes.
• A feature branch got abandoned or replaced by another approach.
• Your local branch is outdated and you want to re-create it from a remote version.

In these cases, keeping around unmerged branches just clutters your branch list. Deleting them helps keep things tidy and focused.

Just remember:

• Only force-delete branches you're sure you don't need.
• Make sure no one else is working on that branch, especially if it's shared.
• Double-check the branch name before hitting enter.

That’s basically how you safely handle force-deleting Git branches. It’s a small command, but powerful — so use it wisely.
