gVim showing carriage return (^M) even when file mode is explicitly DOS

Question

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

Answer 1

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).
