首先到github上面创建一个仓（或者下载其他人创建的也行）。

[root@CSDN /home/Sudley/github]#git clone https://github.com/Sudley/git_learning.gitCloning into 'git_learning'...warning: You appear to have cloned an empty repository.[root@CSDN /home/Sudley/github]#lsgit_learning[root@CSDN /home/Sudley/github]#cd git_learning/[root@CSDN /home/Sudley/github/git_learning]#ls[root@CSDN /home/Sudley/github/git_learning]#

将github仓库clone到本地，A表示仓库节点

[root@CSDN /home/Sudley/github/git_learning]#vi bs.html[root@CSDN /home/Sudley/github/git_learning]#git status  #查看仓库状态，可以看到新增文件是未跟踪状态# On branch master## Initial commit## Untracked files:#   (use "git add 
   
    ..." to include in what will be committed)##       bs.htmlnothing added to commit but untracked files present (use "git add" to track)[root@CSDN /home/Sudley/github/git_learning]#git add bs.html[root@CSDN /home/Sudley/github/git_learning]#git status# On branch master## Initial commit## Changes to be committed:#   (use "git rm --cached 
    
     ..." to unstage)  #若不想提交此新文件可以使用git rm --cached bs.html移除上面add操作的效果##       new file:   bs.html#[root@CSDN /home/Sudley/github/git_learning]#git commit -m "add bs.html"*** Please tell me who you are.Run  git config --global user.email "you@example.com"  git config --global user.name "Your Name"#to set your account's default identity.Omit --global to set the identity only in this repository.fatal: unable to auto-detect email address (got 'root@bogon.(none)')[root@CSDN /home/Sudley/github/git_learning]#git config --global user.name ******[root@CSDN /home/Sudley/github/git_learning]#git config --global user.email ******@**.com[root@CSDN /home/Sudley/github/git_learning]#git commit -m "add bs.html"[master (root-commit) 67ffb78] add bs.html 1 file changed, 30 insertions(+) create mode 100644 bs.html[root@CSDN /home/Sudley/github/git_learning]#git status# On branch main# Your branch is ahead of 'origin/main' by 1 commit.   #提示本地分支比远程分支多一个commit#   (use "git push" to publish your local commits)#nothing to commit, working directory clean[root@CSDN /home/Sudley/github/git_learning]#
    
   

此时远程仓和本地仓的节点状态如下，本地的比远程仓多一个节点

[root@CSDN /home/Sudley/github/git_learning]#git pushCounting objects: 4, done.Compressing objects: 100% (3/3), done.Writing objects: 100% (3/3), 757 bytes | 0 bytes/s, done.Total 3 (delta 0), reused 0 (delta 0)To https://github.com/Sudley/git_learning.git   9df625b..cd78fde  main -> main[root@CSDN /home/Sudley/github/git_learning]#git status# On branch mainnothing to commit, working directory clean[root@CSDN /home/Sudley/github/git_learning]#

Tips：新增文件时需要先git add后再commit，如果是修改原文件且一次性提交所有修改则可以使用git commit -am命令替代git add xx和git commit -m。
