You are talking to a dude with 40+ years of Unix experience, supporting
commercial products most of that time. I didn't get "lucky at Russian
Roulette", I wrote scripts that were portable. I have 40 year old scripts
that _still_ work and they work on virtually every Unix ever built.
How do I know? I was a contractor for my first job, I got plopped down
in front of every random unix you could imagine and each time I polished
off the warts.
I spent decades supporting my own products on every flavor of Unix and
processors from Arm to System/360. Oh, and Windows XP and on and MacOS.
My scripts worked with /bin/sh being whatever it was.
It's interesting to me that other old timers, like Clem, are saying
exactly the same thing as I am. Are we all wrong?
