rm -rf

Finest compression avaliable under UNIX/Linux! Unfortunatly, there is no decompressor avaliable. Command issued on unix systems to remove a directory. If nothing is added after the final slash (/) it will remove the root filesystem. Although, many systems now have protection in place which will report back and say 'rm of / is not allowed' or similar. The command can only be issued by the root user. If you do it as a normal user, it will only remove your home directory and files you have write/execute access to.
