Problem

I want to do: But, since only the root user has write permission to this file, I can't do that. But the following also doesn't work. Is there a way to append to a file in that situation without having to first open it with a 'd editor and then appending the new content by hand?

Error Output

sudo echo "something" >> /etc/config_file
