Bodhi - Kernel update via bash - My suggestion. Your opinion?


Because I consider it quite annoying to type in the name of each of the 5 kernel packages, when installing (or removing) a new kernel, I created a bash script to make it easier.
What do you think about it?

Code:
 Install kernel:
*****************

read -p "Please enter kernel number: `echo '\n> '`" a
sleep 1
echo

sudo apt install linux-headers-"${a}" linux-headers-"${a}"-generic linux-image-"${a}"-generic linux-modules-"${a}"-generic linux-modules-extra-"${a}"-generic
sleep 2
echo

read -p "Please close with the Enter-key ... " Enter
and here the script for removing the kernel:

Code:
 Remove kernel:
****************

read -p "Please enter kernel number: `echo '\n> '`" a
sleep 1
echo

sudo apt purge linux-headers-"${a}" linux-headers-"${a}"-generic linux-image-"${a}"-generic linux-modules-"${a}"-generic linux-modules-extra-"${a}"-generic
sleep 2
echo

read -p "Please close with the Enter-key ... " Enter
I did this, because ukuu failed to install a kernel lately.

what happens if I enter "K" ?

what happens when user tries to uninstall a kernel that does not exist?


some things for you to play with

Code:
apt list linux-{image,header}*
apt list --installed linux-{image,header}*
maybe you could show the user some options based on what you find.

These two scripts are not supposed to replace ukuu.
I assumed, you know already (for example from the grub menu or from Synaptic) what kernels have been installed before.

To prevent a non-existing kernel from being uninstalled, you might look it up in Synaptic, by entering only the number of the one you intent to uninstall.
If it is there, go ahead using the 2nd script, if not, you're done already.

If you enter a "K", nothing happens until you hit the Enter-key.

These two scripts are just supposed to be helpful for installing a kernel, just to see if it fixes some issues, you are currently facing.
In case the new kernel doesn't fix anything, You usually know which one you just installed and then you can use the 2nd script to uninstall it again.

If you think, you should add some features, feel free to go ahead, please.
Any improvement is welcome, of course.

I guess, the two commands should also list the modules, so it would be:
Code:
apt list linux-{image,headers,modules}*
apt list --installed linux-{image,headers,modules}*
The problem as I see it, is that this list can get quite confusing, because it doesn't list the packages sorted by version numbers.

if I enter "k" and hit enter
your list of commands wastes some time and does nothing
same with the uninstall


What you have is a great project to teach yourself how to write a shell script.

What you don't have ( yet ) is a shell script.

this is not how I would *actually* do it, but
as example
Code:
< <(apt list linux-{image,headers,modules}*) awk '{print $2," ",$3}'|sort -u

I don't know what you are doing, but her it does exactly what it is supposed to.
