How to turn off the “CRLF will be replaced by LF” warning

CRLF: Line breaks in windows environment

LF : Line breaks in linux environment

The meaning of this error is that there are two newline characters in the file, git will automatically replace CRLF with LF, so a warning is given.

warning: CRLF will be replaced by LF in [File] . The file will have its original line endings in your working directory.

Turn the auto-conversion feature off in the settings
