You can also use Visual Mode if you don't want to count lines :

Press [v] to enter Visual Mode
Use arrows to select all the lines you want to comment
Then type the following command :

:'<,'>s/^/#/g

:'<,'>s/^#//g

UNLOCK THE ROOT ACCOUNT IN UBUNTU 9.10

Hi friends,
As we know root account is disabled in ubuntu 9.10 by default. There are some advantages in login as root. We cannot unlock root account in this ubuntu release as before. Have a look at this method, this will be useful.
1.If you have already created your root password by using the command Terminal > sudo passwd root, you just have to deactivate auto-login in gnome.
2.To do that go to
System > Administration > Login screen > Unlock > ‘Show the screen for choosing who will login’. > Close.
3.Once you did that Log out of your account.
Choose ‘Other’ from the login screen and log in as root.
4.You won’t be asked for a password at any other time except login.
5.To activate all the options that the Ubuntu has deactivated,
go to
System > Administration > Users & Groups > root > Properties > User privileges, and click everything.
I hope this will help you …. please pass it on…
cheers,
Dharanitharan.A
