in thread /usr/bin/perl -w?

And Unix commands in general, too! Because of shell design and such, typing rm * in a directory which contains a file named -rf could delete everything (except the file -rf)! You should do rm -- * instead. I have actually been bitten by this once or twice, but luckily not by -rf but something more mundane.

I've seen some people use this to their advantage too, by creating files called '-i' in directories containing things they don't want to lose. That way an inadvertant rm * will become interactive.
