Buried in a package called expect is a utility that seems to have a lot of potential: kibitz.
Or at least, it should have had some potential, when it started out in this world way back in 1994. 😯
(I know, that’s a lousy screenshot. I don’t know what I’d show if I did get kibitz running though. Stock photo of two people typing at computers? 🙄 )
If I understand it correctly, it should allow two users to piggyback in the same shell, watching each other type and offering help when necessary.
For me, it didn’t seem to want to work; I tried to kibitz from root to the kmandla account, but kept getting “write permission” messages.
I think I understand how it should work though, and I like the idea, generally speaking. Although two people typing in the same shell sounds like a recipe for a wheel war.
I did have better luck with screen -X though, many long years ago. If kibitz is still doing as it promised almost 20 years ago, it’s a worthy application no matter what I say. 😯
