I tried mr out on Bash on Windows. I found that mr does not work so well.

Steps to reproduce the problem:

15:12:57 Andrew@LAPTOP-V9S562AR:~
$ mr s
mr s: /home/Andrew/.config/vcsh/repo.d/author.git
mr s: received signal 127

The status action does not cover a number of my repos, it just stops at the first repo.

I have installed mr via sudo apt-get install mr.
