One-liner ssh-keygen and ssh-copy-id for Windows powershell

ssh-copy-id.ps1

ssh-keygen && cat $env:userprofile/.ssh/id_rsa.pub | ssh user@linuxserver 'cat >> .ssh/authorized_keys'

Don't know what you mean by the slashes since what is being piped to the ssh command is the content so slashes should have no impact.

usually windows have '\' and linux and unix have '/' so i was concerned. It seems, when used with $env:USERPROFILE , either / or \ is fine.
i also followed chris's article on https://chrisjhart.com/Windows-10-ssh-copy-id/#copy-ssh-key-to-remote-linux-device

Thanks for the help

Since google took me here when searching for a powershell ssh-copy-id, I thought I'd share my modifications to the above which allows for configurable host and uses default ssh pub key as well as ensuring permissions are correct (I just stick this in my profile script):

function ssh-copy-id($server) {
    type $env:USERPROFILE\.ssh\id_rsa.pub | ssh $server "mkdir -p ~/.ssh && chmod 700 ~/.ssh && cat >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys"
}

Thank you very much for sharing this!
