ssh-copy-id is a popular shebang bash script to make it easy to deploy public keys on target machines for key based authn.
The problem is that this script uses the POSIX shell cmd exec which is unknown to powershell:
This can block adoption of powershell as the default shell (via chsh)
Steps to reproduce
PS> ssh-copy-id user@host
Expected behavior
Success
Actual behavior
ssh-copy-id user@host/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
