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'

Thanks!

There is a typo!?

Before the pipe( | ) , $env and userprofile must have : in between.
Also all the / is replaced by \ , before the piping into linux server.
ssh-keygen && cat $env:userprofile\.ssh\id_rsa.pub | ssh user@linuxserver 'cat >> .ssh/authorized_keys'

I Recommend :

ssh-keygen -o -a 100 -t ed25519 -f id_ed25519.pub -C "user@windowsclient" && cat $env:USERPROFILE\.ssh\id_ed25519.pub | ssh user@linuxserver "mkdir ~/.ssh/ ; touch ~/.ssh/authorized_keys ; cat >> ~/.ssh/authorized_keys"

Goodluck

Thanks, I added the : to the env var. 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. I'll keep the command shorter and ppl can feel free to add more specific params if they want =)

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
