Yes.

When I first started in the industry my colleagues told me that I should be using the read-mail program. It has a mode that allows you to use regexps to read your mail really fast. I was told that the normal way to run read-mail with the "really fast" mode was:

rm -rf *

Disclaimer: For the Unix impaired, this is an "expert only" utility. I am not responsible for the loss of all the files in your home directory should you attempt to use it.

Do NOT suggest people try a command which will recursively remove all files ignoring file permissions. Most people will be aware of the hazard. Those who aren't will suffer irreparable harm.
