shutdown the machine

• sudo without pswd

 pet@girl:~$ sudo visudoer  #"vim /etc/sudoers" is dangerous
 

now add one line

 pet ALL=(ALL)NOPASSWD: ALL
 

now I can "sudo -i" without typing password

• so I

 pet@girl:~$ sudo vim /usr/bin/gohome
 

and have this in this file

 sudo init 0
 

so next time I want to shutdown the machine, all I need is

 pet@girl:~$ gohome
 

Format disk

• check dev/

$cd /dev
$ls s-
 

• plug mp3

$ls s-
 

• umount

 umount /media/disk-1         //not always disk-1
 

• then

 mkfs.vfat -I /dev/sdb
