如何從臨時區域中刪除單個文件（撤消git add）？ - How do I remove a single file from the staging area (undo git add)?

問題：

Situation: I have a Git repository with files already in the index. 狀況：我有一個Git存儲庫，其中的文件已經在索引中。 I make changes to several files, open Git and add these files to my staging area with "git add ." 我對幾個文件進行了更改，打開Git並使用「 git add」將這些文件添加到個人暫存區中。

Question: How do I remove one of those files from the staging area but not remove it from the index or undo the changes to the file itself? 問題：如何從登臺區域中刪除這些文件之一，而不從索引中刪除它或撤消對文件自己的更改？
