Hi there, I'm a real newbie to linux, I have redhat 9.0 and I have been updating the programs fron rehats site. I am wondering how I go about unistalling programs I have decided I don't want? I chose to install a new kernel, that was ok but when I thried installing the source it crashed saying rpm fault(or something like that) I have found that certain things don't work without the source so how can I delete the new kernel?

Thanks

It depends on what you did with the old kernel. If the old kernel still exists then you can use rpm -e (read man rpm) to remove the new kernel. Then change your bootloader (grub or lilo).

If the old kernel is gone then install the old kernel again, remove the new kernel, and change your bootloader.

If you are unsure of what you have installed then use rpm -qi and rpm -qa to find out what you have (again read man rpm).

I don't understand the connection you are making here between source and kernel. Could you elaborate on the problem?
