    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。

    $ cat FETCH_HEAD
