\r\n, \r and \n what is the difference between them?
I need to ask about the difference in a string between
\n. How is a string affected by each?
I have to replace the occurrences of
\n but I cannot get how are they different in a string...
I know that
\r is like hitting enter and
\n is for a new line.
\r= CR (Carriage Return) → Used as a new line character in Mac OS before X
\n= LF (Line Feed) → Used as a new line character in Unix/Mac OS X
\r\n= CR + LF → Used as a new line character in Windows

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
\nmoves to the beginning of the line.
\r\n(End Of Line) → a combination of
They are normal symbols as 'a' or 'ю' or any other. Just (invisible) entries in a string. \r moves cursor to the beginning of the line. \n goes one line down.
As for your replacement, you haven't specified what language you're using, so here's the sketch:
someString.replace("\r\n", "\n").replace("\r", "\n")
A carriage return (
\r) makes the cursor jump to the first column (begin of the line) while the newline (
\n) jumps to the next line and eventually to the beginning of that line. So to be sure to be at the first position within the next line one uses both.
