bash: /opt/arch32/mirrorlist: Permission denied - arch32 help

Hi all.
I'm new to Arch Lin and i'm just trying out things to get to know Arch.
At the moment I'm trying to install a 32 bit subsystem as described here http://wiki.archlinux.org/index.php/Ins … _in_Arch64 but in the second step I get the following error:
"bash: /opt/arch32/mirrorlist: Permission denied"

The wiki says I should do
"sed -e 's/x86\_64/i686/g' /etc/pacman.d/mirrorlist > /opt/arch32/mirrorlist",
but that gives me the error above, so I also tried
"sudo sed -e 's/x86\_64/i686/g' /etc/pacman.d/mirrorlist > /opt/arch32/mirrorlist"
which also doesn't work. What's wrong?

PS: i created /opt/arch32 with "sudo mkdir".

run the sed command as root.

This:

sudo sed -e 's/x86\_64/i686/g' /etc/pacman.d/mirrorlist > /opt/arch32/mirrorlist

gives the sed root permission but not the writing to the file with ">". There is probably a better way to do this but this will work...

sed -e 's/x86\_64/i686/g' /etc/pacman.d/mirrorlist > sudo tee /opt/arch32/mirrorlist

Thanks I will try that out!
I'm sorry if I am being stupid but again im very newt o this, but is there a difference between these two things:
> su
> touch hello.txt
and
> sudo touch hello.txt

I dont fully understand the concept of 'sudo' yet, from what I know sudo gives temporary su permission, but under the real user so the owner in the first case becomes root while the owner in the second case becomes whoever is executing the command - is this not how it is?

there is no difference between those two. The issue is that piping output using ">" is considered a different command by sudo.
