Git 常见问题 - git 文件不区分大小写问题

现象

创建一个 git 仓库 git-test，并提交一个文件 test.go，然后修改文件名的大小写为 Test.go。

$ mkdir git-test
$ cd git-test
$ git init --initial-branch=main
$ touch test.go
$ git add .
$ git commit -m "feat: add test.go"

$ mv test.go Test.go
$ ls
Test.go
$ git status
On branch main
nothing to commit, working tree clean

可以看到 git status 没有发生改变，也就是说本地修改的文件名没有在 git 生效。

解决方法

1. 移除本地缓存

   $ git rm -r --cached test.go
   rm 'test.go'
   
   $ git status
   On branch main
   Changes to be committed:
     (use "git restore --staged <file>..." to unstage)
   	deleted:    test.go
   
   Untracked files:
     (use "git add <file>..." to include in what will be committed)
   	Test.go
   

2. 配置 git 区分大小写

   $ git config core.ignorecase false
   
   $ git add .
   $ git status
   On branch main
   Changes to be committed:
     (use "git restore --staged <file>..." to unstage)
   	renamed:    test.go -> Test.go
   
   $ git commit -m "refactor: rename test.go"
   
   $ git log
   commit 8828b606ebc810bf8510487391cdeff4b86027ee (HEAD -> main)

       refactor: rename test.go
   
   commit d8d4b8716c2000bb2dfec2b6bf873887de76d590

       feat: add test.go
   (END)
