While reading up on how to set up
grub, I came across an article claiming that I need to use one of the following two syntaxes,
echo \(hd0,0\) >> /boot/grub/grub.conf
echo '(hd0,0)' >> /boot/grub/grub.conf
because, at the command line, parentheses are interpreted in a special way. What is special about the parentheses? How are they interpreted?
