Replacing carriage return ^M with Enter

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 character in VIM (to 开发者_如何学Cuse in commnad-line mode).

To replace carriage return character (which is <C-m>) 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 <C-m>, so your initial request is not valid.

:%s/\r//g only works when:

• set ff=unix, which when done, automatically converts all CRLF to LF

• set ff=dos and CR is a rogue char that is not preceded by LF, e.g., inserted with C-V C-M.

  CR in LF CR pairs will not be found.

Therefore, if all you want is to convert every LF CR to LF, you should use:

:set ff=unix
:w

You can replace one character using r<CR> in normal mode.
Or you can enter a "return" in command line mode by typing <C-v><CR>.

In vim session try:

:%s/^M//g

Where ^M is achieved by ctrl+V+M keystrokes together.

Similar to @ZyX and @anubhava, but assuming you're simply trying to remove the pesky carriage returns from a windows file, the following will suffice:

:%s/\r//g

LF: Line Feed

CRLF: Carriage Return and Line Feed

^M : What vim interpretes Carriage Return part as. You can also search it with \r

For my case I wanted not to replace it with any other format of line break (LF or etc.) but just period and whitespace (. ). Because what supposed to be was a new sentence but somehow carriage return involved in. Probably user typo.

From

I'll be there^M
We can talk.

To

I'll be there. We can talk.

What helped me is:

:%s/^M\n/\. 

or

:%s/\r\n/\. 

(there's a whitespace in the end)

Both worked fine for me. \r\n easier to type.

Ctrl+M , Ctrl+V to insert ^M
