git prune, git remote prune, git fetch --prune 三者異同

遠端分支的3種狀態
- 遠端倉庫確實存在分支dev
- 本地版本庫（.git）中的遠端快照
- 和遠端分支建立聯絡的本地分支
- Prune all unreachable objects from the object database
unreachable objects 指的是.git\objects中沒有被使用的hash檔案

- Deletes all stale remote-tracking branches under .
- 會清理掉狀態2中的遠端庫已被刪除的遠端分支，本地庫仍存在的 stale remote-tracking branches

- 接下來，在github中刪掉dev分支，此時本地版本庫中的資料快照仍然有dev分支
- git remote prune 會與遠端庫進行一次同步，最終清理掉版本庫中的dev分支，但本地工作區中的dev分支並不會刪除。。

- Before fetching, remove any remote-tracking references that no longer exist on the remote
- 同git remote prune
刪除本地分支
git branch -d/D dev -D 強制刪除
