Do you even google?

Mal wieder Zitat Stackoverflow:
All 3 of them represent the end of a line.
But...\r (Carriage Return) - moves the cursor to the beginning of the line without advancing to the next line
\n (Line Feed) - moves the cursor down to the next line without returning to the beginning of the line - *In a nix environment \n moves to the beginning of the line.
\r\n (End Of Line)- a combi of \r and \n
