• git add
• git commit -m ""
• git push
• git remote add origin [email protected]:----/repoName.git
• git remote remove origin
• git rm -r --cached node_modules

gitignore只能忽略那些原来没被track的文件，如果某些文件已经被纳入了版本管理中，则修改.gitignore是无效的。 解决> 方法就是先把本地缓存删除（改变成未track状态），然后再提交：

• git rm -r --cached node_modules

• git add .

• git commit -m "update .gitignore"

• -r 是为了recursive purpose

• git tag -a -m "first release - use with caution" v0.1-beta
• git push origin v0.1-beta
• git tag
• git branch
• git checkout
• git chceckout
• git checkout -b
• git branch -D
• git log --oneline
• git merge feature-1

merge feature-1 branch to main branch

1. Main as a receiving branch, user need checkout main
2. feature-1 branch will merge into main

• git stash save -m "save msg"

  Stash all uncommitted work

• git stash apply stash{n}
• git stash pop
• git stash drop stash{n}
• git stash list
• git stash clear

merge feature-1 to branch main

• git checkout -b main
• git merge feature-1

• git pull -rebase
• git rebase --onto master server client

  find the common parent of server and client then merge it back to master branch

• git checkout master
• git merge client
