Sudo tee? why u no use the '>>'

cuz you need to be root running those commands to get redirection to a file that is owned by root.

baz@marceline:~$ echo "FOO" >> /etc/libvirt/ZOMG
bash: /etc/libvirt/ZOMG: Permission denied

baz@marceline:~$ sudo echo "FOO" >> /etc/libvirt/ZOMG
bash: /etc/libvirt/ZOMG: Permission denied

baz@marceline:~$ echo "FOO" | sudo tee /etc/libvirt/ZOMG
FOO

I see makes sense.
