.git

这是我在 github 上的一个测试仓。

这是仓的详细信息。

先克隆到本地。

.git/COMMIT_EDITMSG

　　我本地切换到 i44分支，提交过一次commit，-m 跟着的就是 test2

zuo@DESKTOP-QN47U5R MINGW64 /d/a/test/.git (GIT_DIR!)
$ cat COMMIT_EDITMSG
test2

 .git/config

zuo@DESKTOP-QN47U5R MINGW64 /d/a/test/.git (GIT_DIR!)
$ cat  config
[core]
        repositoryformatversion = 0
        filemode = false
        bare = false
        logallrefupdates = true
        symlinks = false
        ignorecase = true
[remote "origin"]
        url = https://github.com/factsbenchmarks/test.git
        fetch = +refs/heads/*:refs/remotes/origin/*
[branch "i22"]
        remote = origin
        merge = refs/heads/i22

　　解释：filemode：当设为True时，即便文件内容没有变化，文件 chmod 权限改动，git status 也会飘红。 设为 False后，上述情况不会发生。

.git/description

zuo@DESKTOP-QN47U5R MINGW64 /d/a/test/.git (GIT_DIR!)
$ cat description
Unnamed repository; edit this file 'description' to name the repository.

.git/FETCH_HEAD

　　之前的操作是

　　　　git checkout i55

　　　　git fetch origin i55

　　　　git rebase origin/i55　　　　　

　　这三步走完后，本地的 i55 分支 和 远程的 i55 分支同步一样了，之前是不一样的。
