我读到在Git中重命名文件时，你应该提交任何更改，执行重命名，然后展示重命名的文件。Git将从内容中识别文件，而不是将其视为一个新的未跟踪的文件，并保留更改历史。

然而，今晚这样做，我最终恢复到git mv。

> $ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#    modified:   index.html
#

我重命名我的样式表在Finder从iphone.css到mobile.css:

> $ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#    modified:   index.html
#
# Changed but not updated:
#   (use "git add/rm <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#    deleted:    css/iphone.css
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#    css/mobile.css

所以Git现在认为我删除了一个CSS文件，并添加了一个新的文件。这不是我想要的。让我们撤销重命名，让Git来完成这项工作。

> $ git reset HEAD .
Unstaged changes after reset:
M    css/iphone.css
M    index.html

我又回到了开始的地方:

> $ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#    modified:   index.html
#

让我们用git mv代替:

> $ git mv css/iphone.css css/mobile.css
> $ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#    renamed:    css/iphone.css -> css/mobile.css
#
# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#    modified:   index.html
#

看起来我们没事了。那么，为什么Git在我第一次使用Finder时没有识别出这个重命名呢?
