Ah ah! I remember two years ago when I type the vi_ command out of curiosity on my laptop, and I didn't live on the first time! Then I learned a big lesson. Don't type commands without thinking a bit before... First I was a bit pissed off at vi_ (well, of course I didn't backup some important staff), thinking (why this a$...le put these kind of commands as signature?), but well it was my fault to be stupid, I could only blame this on me. I hope you learned a lesson too...
