I popped in the floppy did D: and typed `ls`... and error, and the whole class laughed at me. Having been switching a lot lately I typed, I believe, `echo dir > C:\Windows\ls.bat` and (or whatever the right pipe command is, it's been a while), and typed `ls` again. Then double birded the whole class. And started launching the demo.
There were audible gasps esp from the professor who was like, hold up, what did you just do. So I spent 3 minutes explaining it to the class, then we did our demo.
I was at the time quite proud of them all being flabberghasted while I also flipped off over 75 students, actually still am.
Me too son, me too.
For all its faults, IMHO that's the greatest strength of Unix-alike philosophy: making small hacks easy, if you know how the system is composed.
