How to delete old kernel


Hi, Linux noob here... I have just installed RedHat 9 and during installation process downloaded and installed all suggested updates. I believe this is when kernel was updated from 2.4.20-8 to 2.4.20-19.9

But now during during startup in OS select menu, I get 3 choices: Dos, Linux 2.4.20-8 and Linux 2.4.20-19.9... It might be confusing to other users. How do I fix it so that only latest version shows up in the menu and delete old stuff so it doesn't take up space?

Also:

how do I view Linux logical drives? For example total space, free space, etc

Thanks

Do you use LILO or Grub?
Just remove the stanza for the one you don't want in you lilo.conf or grub.conf. For LILO you have to run lilo to apply the changes.

Yes, you can use the Run Command, but I suggest opening a terminal window.
In the Menu, look in System Tools and click on Terminal.

In the terminal, type:
Code:
rpm -e kernel-2.4.20-8

You dont remove rpm -e kernel-source-2.4.20-8..this is the command you type in console as root in order to remove the package(which, in this case is your old kernel)

ok I ran those 2 lines:

[serge@localhost serge]$ rpm -e kernel-2.4.20-8
error: cannot get exclusive lock on /var/lib/rpm/Packages
error: cannot open Packages index using db3 - Operation not permitted (1)
error: cannot open Packages database in /var/lib/rpm
[serge@localhost serge]$ rpm -e kernel-source-2.4.20-8
error: package kernel-source-2.4.20-8 is not installed

does serge not have enough priviliges? I made the user part of adm group.

also where do I find grub.conf ? I tried searching for this file from root directory, but it says I need to run updatedb, which it seems I also don't have enough privileges

[serge@localhost serge]$ updatedb
fatal error: updatedb: You are not authorized to create a default slocate database!


aahh.. I feel like fish out of water, bear with me peeps.. also is there any good documentation on this stuff? like what the heck is rpm and etc?

Thank you.

Here, do this in console:

su -
this will prompt you for the root password. Input that and then do the above 2 commands that I gave you. in linux there are permissions to every file and directory..so you have to be root to do maintainence on your system (ex installing programs and removing them....etc etc.)

ok well you have to be root to install/uninstall rpm packages so "su -" to root and then uninstall it, also you have to be root to run updatedb....and the grub.conf file is in the /etc folder, oh and once again you have to be root to edit it

so before tackling any of these three things you want to do
type :
su -
and then the root password and then go about your business

show the steps you've taken to edit it from logging in as root right to the point of trying to save it.
