Common problems when using Git

When windows uses git, the initial words appear: warning: LF will be replaced by CRLF
The newline in windows is CRLF, and the newline in linux is LF, so a prompt appears when executing add . The solution:

$ rm -rf .git  // 删除.git  
$ git config --global core.autocrlf false  //禁用自动转换 

Then re-execute:

$ git init    
$ git add .
