Unix system, the end of each line only "< line >", that is "\ n", the Windows system, each line at the end of the "< newline >< Enter >", that is "\n\r", Mac system, the end of each line is "< Enter >". A direct consequence of this is that if the file under the Unix/mac system is opened in Windows, all the text will be turned into one line, and if the files in Windows are opened under Unix/mac, a ^m symbol may appear at the end of each line. So, if you need to work on a cross-platform text file, you might get a bit bigger with a carriage return line.
0x0D (ASC code is 13) refers to "carriage return" \ r is to place the cursor at the beginning of the bank
0x0A (ASC code is 10) refers to "newline" \ n is the same column where the cursor is placed on the next line
0x0D + 0x0A return line \ r \ n Place the cursor at the beginning of the next line
\ n is a newline, English is Linefeed,ascii code is 0xA.
\ r is the carriage return, English is carriage return, ASCII code is 0xD.
