The first (and usually last) time that you accidentally run "rm -rf *" in the wrong directory (usually / ) will make it obvious why you don't want to be root all the time. Actually, a much better example is something like: rm -rf * .o The reason is that most people will react to "rm -rf *" by saying "Well, I've never typed such a thing in any directory, so what's the big deal?" But they probably have typed something like rm -rf *.o A lot of users will have trouble spotting the difference between these, but of course the first is likely to be a disaster, while the second is a fairly routine command for a C programmer. The keyboard that I'm using to type this is one that seems to like to insert spaces at unusual places, presumably because the space bar is much more sensitive than other keys. OTOH, the 'a' and quote keys often don't work. Lots of people can relate to flakey keyboards. - Subcription/unsubscription/info requests: send e-mail with "subscribe", "unsubscribe", or "info" on the first line of the message body to discuss-request at blu.org (Subject line is ignored).
