Permission denied for root user

shujja · 07-04-2005, 12:40 AM

Hi everybody,

When i login as a root in redhat9, and write any command such as /boot/grub/grub.conf or gedit /etc/inittab, system gives following message
-bash: permission denied.

Plz help me.

Do you mean logged in as the root user or logged in as a regular user using su in the terminal?

If the second option is the case, try using:

su -

instead of just

su

Are you sure you have permissions to write the file. Do a ls -l on files and make sure you don't have some like r--r--r--. Then you have to change the permission using the chmod command.

Well, for the first "command" I understand why you'd get
permission denied, /boot/grub/grub.conf is most likely not
executable, and therefore even root can't run it.

For the "gedit /etc/inittab" I'd like to see a copy & paste of the
actual screen session.

Cheers,
Tink

Check the permissions of the files,if proper pemissions are not there set the permission as root.

hi,
I deleted a user after upgrading from redhat 8 to 9 and I cannot delete the Xauthority files of that user even as root from both the Xwindow and console(bash).
I got the same error access denied.

If you are already in the root, why do you want to do a su to root again? Also, if you are already as the root,
when you do a su (or su - ), you will not be asked for the password.

That depends on the situation. The main difference of a su and a su - is that, the .bashrc (i assume u use bash) will
be executed (or rather sourced

) when you do a su -.

HTH.
