4.3.4 推送和拉取

名称解释和对应使用场景：

• 推送：从本地到远程仓库，本地新增文件，推送到远程仓库。

• 克隆/下载：从远程仓库到本地，本地不存在对应的仓库。

• 拉取：从远程仓库到本地，本地已经存在，远程仓库上新增了文件，使用拉取。

  操作演示

1. 进入克隆目录，添加新文件

   xxxxxxxxxx
   Administrator@SC-201911261404 MINGW64 /d/GitSpace/second_git_repos (master)
   $ cd first/
   Administrator@SC-201911261404 MINGW64 /d/GitSpace/second_git_repos/first (master)
   $ pwd
   /d/GitSpace/second_git_repos/first
   Administrator@SC-201911261404 MINGW64 /d/GitSpace/second_git_repos/first (master)
   $ vim Hello.java
   Administrator@SC-201911261404 MINGW64 /d/GitSpace/second_git_repos/first (master)
   $ cat Hello.java
   public class Hello{
       public static void main(String[] args){
           System.out.println("hello worlod");
       }
   }
   

2. 执行 git add . 将工作区所有内容上传到暂存区

   xxxxxxxxxx
   $ git add .
   warning: LF will be replaced by CRLF in Hello.java.
   The file will have its original line endings in your working directory
   
   Administrator@SC-201911261404 MINGW64 /d/GitSpace/second_git_repos/first (master)
   $ git status
   On branch master
   Your branch is up to date with 'origin/master'.
   
   Changes to be committed:
     (use "git restore --staged <file>..." to unstage)
           new file:   Hello.java
   
   
   Administrator@SC-201911261404 MINGW64 /d/GitSpace/second_git_repos/first (master)
   

3. 执行git commit -m ‘本次提交的注释’ 提交到本地仓库

   xxxxxxxxxx
   $ git commit -m "commit 1" Hello.java
   warning: LF will be replaced by CRLF in Hello.java.
   The file will have its original line endings in your working directory
   [master 758fefc] commit 1
    1 file changed, 5 insertions(+)
    create mode 100644 Hello.java
   

   此时去gitee上查看，没有发现Hello.java。

4. 执行git push [别名] [分支名] 其中别名和分支名可省略。将本地仓库所有内容上传到远程仓库码云 ，码云刷新可看到最新内容

   xxxxxxxxxx
   $ git push https://gitee.com/gtjinxf/first.git master
   

   

   xxxxxxxxxx
   #出现一下提示，表示push成功

   Counting objects: 100% (4/4), done.
   Delta compression using up to 8 threads
   Compressing objects: 100% (3/3), done.
   Writing objects: 100% (3/3), 427 bytes | 427.00 KiB/s, done.

      7845ca7..758fefc  master -> master
   
   Administrator@SC-201911261404 MINGW64 /d/GitSpace/second_git_repos/first (master)
   

5. 在gitee上新建一个文件UserVo.java

   

   

6. git pull 拉取远程库内容

   xxxxxxxxxx
   $ git pull https://gitee.com/gtjinxf/first.git master
   remote: Enumerating objects: 4, done.
   remote: Counting objects: 100% (4/4), done.
   remote: Compressing objects: 100% (3/3), done.
   remote: Total 3 (delta 1), reused 0 (delta 0), pack-reused 0
   Unpacking objects: 100% (3/3), 331 bytes | 1024 bytes/s, done.
   From https://gitee.com/gtjinxf/first
    * branch            master     -> FETCH_HEAD
   Updating 758fefc..b182a56
   Fast-forward
    UserVo.java | 4 ++++
    1 file changed, 4 insertions(+)
    create mode 100644 UserVo.java
   

7. 本地D:\GitSpace\second_git_repos\first目录下查看，发现多出一个UserVo.java,内容和在gitee上添加的内容一样。
