Error "bash: /dev/fd/62: No such file or directory" with MinGW (git bash)

Hello!

I get the following error when running z in MinGW (git bash 2.23 on Windows 10): bash: /dev/fd/62: No such file or directory

I added a set -x in _z to see what line outputs this, but I doesn't seem obvious to me. Here is the full output:

I get the same error (on windows)

I had a similar error, from a bit of a google it appears that the mingw filesystem does not support certain file descriptors, so you have this issue running some commands on git bash, but wouldn't running them on a proper linux machine: https://github.com/bats-core/bats-core/issues/256

This happens on some installations and does not occur on others. This fixed it for me: rm /dev/fd && ln -s /proc/self/fd /dev/fd
