new Mac OS has ssh-copy-id builtin that handle more key type and more ssh server like dropbear. You should run shellcheck on you code because it has quoting issue. You should try to use more recent algorithm like rsa or even better ed25519.

Hey @Et7f3 it befuddles me to wonder why - or even how - you found this piece of code I wrote 12 years ago. But I learned a lot from your feedback. Thank you!

I searched upstream of mac os ssh copy id to fix something. Apparently it is bsd repo. And I found your gists with google.
