I must be getting old, as I can't remember a single time I accidently told a production system to close up the shop. Maybe it was starting out as an operator in a commercial data center with many paying customers using RJE around the clock, then TSO was added to the mix. But I learned UNIX well before sudo and still do root business logged on as root (with a RED background color). UNIX _does_ make you respect its power, CP and CMS less so (we won't mention those other OSes). ;-) -- May the LORD God bless you exceedingly abundantly!
