status

接着之前初始化的仓库，我们在MyProject目录下右键打开Git bash，运行git status命令看看会出现什么东西。

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git status
On branch master
nothing to commit, working tree clean

我们往README.md里面添加一些内容，再运行git status命令查看结果

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git status
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   README.md #注意这里是红色的
        
no changes added to commit (use "git add" and/or "git commit -a")

git status命令可以输出仓库当前的状态，上面的命令输出告诉我们，README.md已经被修改过了，但还没有对修改进行提交。
接下来，我们使用git diff命令查看具体修改了什么内容。

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git diff
warning: LF will be replaced by CRLF in README.md.
The file will have its original line endings in your working directory
diff --git a/README.md b/README.md

--- a/README.md
+++ b/README.md

 Hello Git!

通过git status命令我们知道了哪些文件进行了修改，并且git diff还可以告诉我们具体修改了哪些内容。这样我们就可以安心的把它们提交到仓库了。
第一步，先用git add命令，命令行没有输出什么提示，我们再用git status命令看看发现‘modified: README.md’已经从红色变为绿色了。

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git add README.md

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git status
On branch master
Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
        modified:   README.md # 注意这是绿色的

第二步，使用git commit进行提交。

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git commit -m "add distributed"
[master 668e5ad] add distributed
 1 file changed, 1 insertion(+)

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git status
On branch master
nothing to commit, working tree clean

小结

初始化一个 Git 仓库，使用 git init 命令。
添加文件到 Git 仓库，分两步: 使用命令git add <file>，可反复多次使用，添加多个文件；使用命令 git commit -m <message>完成提交。

案例

我们创建几个文件在工作目录里面，使用git status命令输出仓库当前的状态

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ touch index.php login.php

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git status
On branch mastergit 
Untracked files: #未被追踪的文件
  (use "git add <file>..." to include in what will be committed)
        index.php
        login.php

no changes added to commit (use "git add" and/or "git commit -a")

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$

下面，我们对index.php文件的修改追踪，再通过git status命令查看当前仓库状态

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git add index.php

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git status
On branch master
Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
        new file:   index.php #注意这是绿色的

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        login.php #注意这是红色的

我们把login.php也一并提交到仓库

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git add login.php

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git commit -m "add tow files"
[master ea56a43] add tow files
 2 files changed, 0 insertions(+), 0 deletions(-)

 create mode 100644 login.php

23696@DESKTOP-GKRBCVI MINGW64 ~/Desktop/MyProject (master)
$ git status
