Shell foot This report wrong line break syntax error near unexpected token \ r

Sometimes some of the improperly processed SH script files in Windows are placed under Linux to perform an error, prompting for a newline character, mainly because the end of the EOL line under window is "\ r \ n" two characters, while Linux,unix is "\ n".

The following VIM commands are confirmed.

: E ++ff=unix% #显示回车符 (\ r), specific in the VIM environment will be displayed as "^m" symbol: Set list #显示换行符 (\ n), the specific re-vim environment appears as "$" symbol. This command also displays tabs, which appear as "^i" symbols in the VIM environment

Remove the carriage return so that the shell script can function correctly

:%s/\r//g
