Could I get some help?

[some11]

Hey!
Could I get some help as well?
Im trying to change this

File:/boot/grub/menu.lst
replace: default 1
with: default 0

so I type in
sudo sed 's/default 1/default 0/' /boot/grub/menu.lst

and it does't give me any errors, but it isn't changing it!

Any help, wouldn't go a miss!
Saying thanks now!

because you have not saved it?
check whether your sed supports the -i option, if not redirect the sed to an temp output file, then rename it back to original.

You can do this using perl without having to redirect the output

perl -pi -e 's/default\ 1/default\ 0/' /boot/grub/menu.lst

or as ghostdog74 said you can use sed -i which will edit the file in place.
