Thanks, I was somehow not recognizing the part where you said
the shell script was named 'rm'.
Yeah, that would take a system down.
Here's one for you. It's happened to me twice, many years ago.
What happens when you want to remove all of the *.txt files in a dir
and are a little slow letting go of the shift key on the *?
You get: rm *>txt
which leaves you with a directory with one empty file in it.
I learned to alter my typing habits after the second time.
