Kernel Load script and some utilities

I have created a little script to help me with some kernel installs and some utilities centered around GRUB.
This is the first version. I will add updates as I go.

Future mods would be to make it more user friendly i.e. handling errors
   I want to script removal of kernels but make it a choice of what kernels are installed.
   This might be better as a python script as it gets more complicated.
   Maybe a better name for the script.

I am not a script expert so I am sure there are better ways to make the code.
Anyway here it is if anyone is interested.
Thanks

Re: Kernel Load script and some utilities

I think I posted this in the wrong place.
Shouldn't it be in Programing and scripting?
Thanks

That's for "programming issues and discussion" so I think "Community Contributions" is better suited for this.
