^M characters in git commit message (git commit -v)

问题

I am having a weird problem where lots of ^M characters show up in my git commit message. Please find a screenshot attached. This is not causing any problems, just makes it annoying to read through.

Tips appreciated.

"The Proper Way", if you use Git in cross-platform environment, contrary to Abhijeet's answer, is:

Learn and CORRECTLY configure core.autocrlf settings in each client

Read local topic "Why should I use core.autocrlf=true in Git?" as good starting point

回答2:

Thats a windows newline. Newlines in and windows & linux are different.

You can remove it using dos2unix.

I'm on windows and did not want to set autocrlf to true. I worked around the issue by putting the following in my .vimrc

" settings for git commit messages
function GitCommitSettings()
    %s/^M//g               " remove ^M added by git diff
    syntax sync fromstart  " refresh syntax highlight after replace
    1                      " move to line 1
endfunction
au BufNewFile,BufRead COMMIT_EDITMSG call GitCommitSettings()
