• learn git(本地仓库)


    #本地

    在Windows上安装Git

    在Windows上使用Git,可以从Git官网直接https://git-scm.com/downloads下载,然后按默认选项安装即可。

    装完成后,在开始菜单里找到“Git”->“Git Bash”,蹦出一个类似命令行窗口的东西,就说明Git安装成功!

    安装完成后,还需要最后一步设置,在命令行输入:

    $ git config --global user.name "Your Name"
    $ git config --global user.email "email@example.com"
    

    创建版本库

    $ mkdir learngit
    $ cd learngit
    $ pwd
    /Users/michael/learngit

    初始化本地仓库

    $ git init
    Initialized empty Git repository in /Users/michael/learngit/.git/

    将文件上传到缓存区或者 git add .  或者git add -A 或者 git add --all

    $ git add readme.txt

    将文件从缓存区提交到版本库

    $ git commit -m "wrote a readme file"
    [master (root-commit) eaadf4e] wrote a readme file
     1 file changed, 2 insertions(+)
     create mode 100644 readme.txt

    查看仓库状态

    $ git status
    On branch master
    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:   readme.txt
    
    no changes added to commit (use "git add" and/or "git commit -a")

    查看某个文件(版本库或缓存区)和工作区中不同

    $ git diff readme.txt 
    diff --git a/readme.txt b/readme.txt
    index 46d49bf..9247db6 100644
    --- a/readme.txt

    $ git reset --hard HEAD^
    HEAD is now at e475afc add distributed

    在Git中,用HEAD表示当前版本,也就是最新的提交,上一个版本就是HEAD^,上上一个版本就是HEAD^^,当然往上100个版本写100个^比较容易数不过来,所以写成HEAD~100

    版本回退到指定版本号

    $ git reset --hard 1094a
    HEAD is now at 83b0afe append GPL

    如果想将回退后的版本强制推送到远程仓库。git push -f origin master

    远程版本强制推送当前分支

    git push -f

     远程版本推送所有分支

    git push --all origin -u

    查找版本号(如果重启机器了)

    $ git reflog
    e475afc HEAD@{1}: reset: moving to HEAD^
    1094adb (HEAD -> master) HEAD@{2}: commit: append GPL
    e475afc HEAD@{3}: commit: add distributed
    eaadf4e HEAD@{4}: commit (initial): wrote a readme file

    撤销修改1(如果让这个文件回到最近一次git commitgit add时的状态)

    $ git checkout -- readme.txt

    撤销修改2(把暂存区的修改撤销掉(unstage),重新放回工作区)

    $ git reset HEAD readme.txt
    Unstaged changes after reset:
    M    readme.txt

    撤销修改3(把版本库的修改撤销掉)

    那只能通过版本回退了

    撤销修改4*(远程的修改撤销)

    祝你好运没乱动代码,没法子

    删除版本库中文件(如果工作区删除了文件,需要版本库也删除)

    $ git rm test.txt
    rm 'test.txt'
    
    $ git commit -m "remove test.txt"
    [master d46f35e] remove test.txt
     1 file changed, 1 deletion(-)
     delete mode 100644 test.txt

     删除git目录下的.git目录

    rm -rf .git
