I got dropped in to an AS/400 environment a few years ago. All my knowledge instantly vanished. It was harrowing.
There were so many idiosyncrasies my coworkers knew that I had to learn (anyone know how to push the F22 key?) The terminal didn't function in any way I was familiar with at all (no ls, cd, mv, nothing). The "filesystem" was basically for interoperability while the actual system ran with a concept of "libraries" instead of folder hierarchy.
I ended up having to take basic lessons on the system.
It really gave me an appreciation for "stupid computer shit we all know". It sucks to be in a position of not knowing that stuff. Suddenly the most basic functions becomes monumental tasks.
