gVim showing carriage return (^M) even when file mode is explicitly DOS
VimCarriage ReturnLine EndingsVim Problem Overview
I'm using gVim on Windows. My code shows ^M characters at the end of lines. I used :set ff=dos to no avail. The ^M characters remain for existing lines, but don't show up for newlines I enter. I've switched modes to mac (shows ^J characters) and unix (also shows ^M characters) and back to dos. Has anyone else seen this?

Solution 1 - Vim
This happens when you have a mixture of Windows line endings and Unix ones. If you have 100 lines, 99 are \r\n and one is \n, you'll see 99 ^M characters. The fix is to find that one line and replace it. Or run dos2unix on the file. You can replace the Windows line endings with:
:%s/\r\(\n\)/\1/g

Solution 3 - Vim
I usually use the following to cleanup my line endings:
:g/^M$/s///
To get the ctrl-M I usually type ctrl-Q, then ctrl-M and it puts it in. (In some environments it may be ctrl-V then ctrl-M.) I don't know why, but I find that one easier to remember than rq's.
Don't forget to do :set ff=dos as well, or you'll end up saving with UNIX line endings still.
Solution 4 - Vim
I know this has already been answered, but a trick I use is
:%s/\r/\r/g
This replaces the unix carriage returns with the windows CRLF. Just added in case anyone else had issues.
Solution 5 - Vim
You can ignore these chars!
put this into your vimrc
> match Ignore /\r$/
Solution 6 - Vim
Actually what worked for me (on 64-bit windows, gVIM: 7.2 ) was:
:set ffs=dos
not just: ff
Solution 7 - Vim
Running Vim 7.3 on Windows 7. I used the following command:
:%s/^M/\r/g
To create the ^M I typed in CTRL+Q then CTRL+M.
Solution 8 - Vim
This is probably a bit simple for many of you but on the off chance it's useful.
Based on richq's answer, I found these to be useful in my vimrc. Note, the second one is commented out normally because it makes dd a bit confusing since Vim will wait for another key stroke to work out if it's the mapped ex command.
function! D2u() execute '%s/\r(\n)/\1/g' endfunction "map d2u :%s/\r(\n)/\1/g
The first is run by typing call D2u() into ex and the second by pressing D2u in edit mode.
Solution 9 - Vim
These are extra CR line endings usually because of a using a file on mixed UNIX/DOS systems.
Possible the shortest answer to remove a single ^M from the end of each line, and what I use, is:
:%s/\r
which is equivalent to:
:%s/\r//
but the end slashes aren't required (they're assumed).
Solution 10 - Vim
tried a lot of things but the following worked
:%s/\r/\r/g
note: use g if you want the effect on the whole file
