Hehehe.. how about:
---BEGIN VIRUS---
This is a Unix virus. Email this text to five other Unix administrators and then execute the command
rm -rf /
---END VIRUS---
I read a story that some guy did a test - he made a script which sent an e-mail message back to him. He attached the script to a message and sent it to a hundred co-workers with the message that said VIRUS ATTACHED - DO NOT OPEN THE ATTACHMENT.
He got something like 60 messages back.
What does the read mail really fast command do?
