Why this msg when i use git commit

git%20commit

Have you tried a commit message using either the -m or -F options?

git commit -m "A message"

You should be able to use atom as your git editor. It looks like it’s not able to find the atom command. I found this on stackoverflow, https://stackoverflow.com/questions/52245901/bash-atom-command-not-found-how-to-resolve-this-in-windows, that might help you. At that point, I think your setup should work.
