Here is that useful post

rm -r is an old chestnut.
ifconfig -a 1 has a surprising impact - at least on Solaris.
Also good on Unix: crontab. Hanging. Now don't terminate with ^D, this will wipe the crontab. Dito with ^C on some buggy implementations.

I remember when I was at university the text editor we were taught to use saved backup files as filename+ampersand. You can guess how that went if you were slightly careless when cleaning up old backups...
