This is a special character, CTRL+M and can be removed using sed or vim. Using vim we can replace/substitute a text with the following command:


Therefore, we should be able to replace ^M, by typing CTRL+V then CTRL+M, with an empty space as so:


Since I have lots of random files containing ^M, it’d be easier to use sed from the command line instead.

❯❯❯ sed -i 's/^M//g' *.md
  • -i or --in-place edit files in place.
