when I typed less /boot/grub2/grub.cfg in tty2 i get permission denied an I did su - password and that did not work I am in fedora 20 64 bit  what did I do wrong

  • Could you please expand upon "that did not work" - did you receive the same permission denied error? Was your password not accepted? It's difficult to answer without the full details. – aliceinpalth Mar 7 '18 at 18:11
  • @aliceinpalth Christopher helped me I was not in root – cinemassacres Mar 7 '18 at 18:13

You failed to change into the root user.

To view that file, you must have root privileges.

You get that by using sudo:

sudo less /boot/grub2/grub.cfg

assuming sudo has been set up and that you have permission to use it. The password that sudo asks for is your unprivileged user's password, not the root password.

If sudo has not been set up, then change into root with

su -

This will also ask for a password, but in this case it's the root account's password.

Once you are root, you should configure your other user so that it can use sudo. You do this using visudo. See the sudo and visudo (and sudoers) manuals.
