Comment 169 for bug 554172

In response to Sepero, message 165 above, could you please clarify the instructions in the second link in your post.

When I run sudo su -, it puts me in root.

In the next step, I'm assuming the words done & exit are not to be included in what I enter into the terminal.
When I run:
sed -i 's/^console output/\#console output/' $file;

I get:
sed: no input files

Obviously I'm doing something wrong. If you would be kind enough to put exacly what needs to be entered into the terminal I will see if this works.

Thank you.
