    原博引起了大家的吐槽:

    从微博看不出该修改是否已经 commit ,在本地测试这几种可能:

    未add 之前,切换分支 修改的代码会丢失;
    add 之后,commit之前,切换分支 修改的代码丢失;
    [AntLinkCampus] git status                                               14:01:51  ☁  develop ☀ 𝝙
    On branch develop
    Changes not staged for commit:
      (use "git add <file>..." to update what will be committed)
      (use "git checkout -- <file>..." to discard changes in working directory)
    
        modified:   CampusServer/apps/web/conf/app.conf
    
    no changes added to commit (use "git add" and/or "git commit -a")
    [AntLinkCampus] git add .                                              14:02:38  ☁  develop ☂ ⚡ 𝝙
    [AntLinkCampus] git status                                             14:02:50  ☁  develop ☂ ✚ 𝝙
    On branch develop
    Changes to be committed:
      (use "git reset HEAD <file>..." to unstage)
    
        modified:   CampusServer/apps/web/conf/app.conf
    
    commit 之后;
    1. 新建分支 git branch <new-branch>
    2. git reset HEAD^ 恢复上一个版本,
    3. git checkout -- <file> 取消更改
    4. 切换分支 git checkout <new-branch>
    5. 提交自己的更改
    [AntLinkCampus] git reset HEAD^                                          14:27:54  ☁  develop ☀ 𝝙
    Unstaged changes after reset:
    M   CampusServer/apps/web/conf/app.conf
    [AntLinkCampus] git status                                             14:28:17  ☁  develop ☂ ⚡ 𝝙
    On branch develop
    Changes not staged for commit:
      (use "git add <file>..." to update what will be committed)
      (use "git checkout -- <file>..." to discard changes in working directory)
    
        modified:   CampusServer/apps/web/conf/app.conf
    
    no changes added to commit (use "git add" and/or "git commit -a")
    [AntLinkCampus] git checkout -- CampusServer/apps/web/conf/app.conf    14:28:50  ☁  develop ☂ ⚡ 𝝙
    [AntLinkCampus] git status                                               14:29:00  ☁  develop ☀ 𝝙
    On branch develop
    nothing to commit, working directory clean
    

    也可以使用以下方法:利用 git stash

    [AntLinkCampus] git stash                                              14:52:44  ☁  develop ☂ ⚡ 𝝙
    Saved working directory and index state WIP on develop: e3be7d3 update
    HEAD is now at e3be7d3 update
    [AntLinkCampus] git checkout -b ch                                       14:52:59  ☁  develop ☀ 𝝙
    Switched to a new branch 'ch'
    [AntLinkCampus] git status                                                      14:53:08  ☁  ch ☀
    On branch ch
    nothing to commit, working directory clean
    [AntLinkCampus] git stash pop                                                   14:53:35  ☁  ch ☀
    On branch ch
    Changes not staged for commit:
      (use "git add <file>..." to update what will be committed)
      (use "git checkout -- <file>..." to discard changes in working directory)
    
        modified:   CampusServer/apps/web/conf/app.conf
    
    no changes added to commit (use "git add" and/or "git commit -a")
    Dropped refs/stash@{0} (e7a4c7e7a126d47ace94184d7a9443eff41d7e84)
    [AntLinkCampus] git add .                                          14:54:01  ☁  
    [AntLinkCampus] git commit -m  'update'                                          14:54:01  ☁  
    

    切回主分支撤销修改

    [AntLinkCampus] git checkout develop                                          14:54:01  ☁  ch ☂ ⚡
    M   CampusServer/apps/web/conf/app.conf
    Switched to branch 'develop'
    [AntLinkCampus] git status                                             14:55:26  ☁  develop ☂ ⚡ 𝝙
    On branch develop
    Changes not staged for commit:
      (use "git add <file>..." to update what will be committed)
      (use "git checkout -- <file>..." to discard changes in working directory)
    
        modified:   CampusServer/apps/web/conf/app.conf
    
    no changes added to commit (use "git add" and/or "git commit -a")
    [AntLinkCampus] git checkout -- CampusServer/apps/web/conf/app.conf    14:55:33  ☁  develop ☂ ⚡ 𝝙
