Replacing carriage return ^M with Enter

Question

I know how to remove ^M in my files (%s/^M//g), but this one is just one line I\'d like to replace ^M with enter... what\'s the enter char

Answer 1

To replace carriage return character (which is ) with line feed character (which is unix line break character) you should run a bit strange command:

%s/\r/\r/g

It looks like if it is doing nothing, but in regular expressions and double-quoted strings carriage returns are represented using \r and line feeds with \n, while in the replacement part of :s command and substitute() function they mean the opposite.

Note that in terminal Enter produces , so your initial request is not valid.
