I have a file which has been edited in windows with an incorrect setting. All the lines have
^M
At the end of each line.
To search for these in Vim, you can type ctrl+v (to mean “take my next key combination literally”) then ctrl+m. To clean up my file I used:
:% s/^M$//
Where the ^M is typed using Ctrl+V, Ctrl+M. I’ve recorded it as a macro as I seem to be fixing the same thing a lot these days. Hope that helps someone!
