Interactive script to update Gentoo install

lazydog · 06-28-2017, 09:50 AM

Hello,

I recently reinstalled Gentoo on a new system and have decided to use an interactive script to do system updated.

Please take a look and let me know if there are any improvements that can be make to it. Thnx.

Code:

#/bin/bash

read -p 'Update the Portage Tree? ' tree

if [ "$tree" == "y" ]
   then
	echo '*******************************'
	echo '*******************************'
	echo '**'
	echo '**  UPDATING PORTAGE TREE'
	echo '**'
	echo '*******************************'
	echo '*******************************'
	echo
	echo
	eix-sync && \
	echo
	echo
fi

read -p 'Check Gentoo Security Advisories? ' glsa

if [ "$glsa" == "y" ]
   then
	echo '*******************************'
	echo '*******************************'
	echo '**'
	echo '**  SECURITY ADVISORIES'
	echo '**'
	echo '*******************************'
	echo '*******************************'
	echo
	echo
	glsa-check -l && \
	echo
	echo
fi

read -p 'Check System Updates? ' check

if [ "$check" == "y" ]
   then
	echo '*******************************'
	echo '*******************************'
	echo '**'
	echo '**  CHECKING SYSTEM UPDATES'
	echo '**'
	echo '*******************************'
	echo '*******************************'
	echo
	echo
	emerge --update --deep --pretend --with-bdeps=y @world && \
	echo
	echo
fi

read -p 'Porceed with System Updates? ' update

if [ "$update" == "y" ]
   then
	echo '*******************************'
	echo '*******************************'
	echo '**'
	echo '**  CHECKING SYSTEM UPDATES'
	echo '**'
	echo '*******************************'
	echo '*******************************'
	echo
	echo
	emerge --update --deep --with-bdeps=y @world && \
	echo
	echo
fi

read -p 'Remove Pckages No Longer Needed? ' cleanup

if [ "$cleanup" == "y" ]
   then
	echo '*******************************'
	echo '*******************************'
	echo '**'
	echo '**  REMOVING OLD PACKAGES'
	echo '**'
	echo '*******************************'
	echo '*******************************'
	echo
	echo
	emerge --ask --depclean && \
	echo
	echo
fi

read -p 'Update ETC Files? ' etc

if [ "$etc" == "y" ]
   then
	echo '*******************************'
	echo '*******************************'
	echo '**'
	echo '**  UPDATING ETC FILES'
	echo '**'
	echo '*******************************'
	echo '*******************************'
	echo
	echo
	etc-update && \
	echo
	echo
fi

echo
echo
echo '*******************************'
echo '*******************************'
echo '**'
echo '**  SYSTEM UPDATE COMPLETE'
echo '**'
echo '*******************************'
echo '*******************************'
echo
echo

You do not have to write 'echo' for every line.

Code:

read -p 'Update the Portage Tree? ' tree

if [ "$tree" == "y" ]
   then
	echo "*******************************
	     ********************************
	     **				   **
             **  UPDATING PORTAGE TREE     **
	     **				   **
	     ********************************
	     ********************************"
	echo;echo
	echo "eix-sync && \""
	echo;echo
fi

Thnx. That would make for less typing.
But because of the indents to the script I need to leave those echo's in there so everything lines up.

Other then that, do I have all the bases covered?

try one and see what it does. it just a matter of formatting the text to show how you want it on your screen.
and if it is doing everything that you want it to, then I'd say yes.

Q: what ifs.

what if you hit the wrong key then what happens?

lazydog · 06-28-2017, 12:06 PM

Thnx. I already know if any key but y is hit the script moves onto the next step in the process.

Code:

Update the Portage Tree? f
Check Gentoo Security Advisories? e
Check System Updates? s
Porceed with System Updates? t
Remove Pckages No Longer Needed? u
Update ETC Files? s


*******************************
*******************************
**
**  SYSTEM UPDATE COMPLETE
**
*******************************
*******************************

Which is exactly what I want.

basics covered, here's some further development ideas to consider.

could include overlay and eix stuff maybe.

glsa stuff maybe too? like to give the option to only ugrade the glsa packages.

also, i wondered about the questions being asked up front, bam bam bam bam bam, before anything happens, so it isnt left waiting for user interaction. so it would be as fast for the user saying "y" to the questions, as "n" (or other).
...and then even have an alternative answer to "y", where "a" for "ask" could still offer the chance to be asked before proceeding at some stage, like where what you might want to do might change depending on the outcome of the previous step.

What do you mean with the eix reference? I do syncing as the first thing in the script.
Overlays... maybe. Haven't really looked into overlays as I am still new to gentoo and its workings

Again I do this in the script so what are you referring to here?

Sometimes it make sense to ask the question right before the action as something that is shown just before might influence your decision on if you should continue or not. If you answered everything upfront you might not want a portion to be completed at the present time because of something that was in one of the outputs.

I have stream-lined the script a bit and added color. When I get home tonight I'll post the new script.

Here is what I have now:

Code:

You miss the keep-going feature. Kinda annoying when portage stops on every package which breaks. like sdl2-mixer which is not fixed for over 2 weeks, open bugs for ages.

And depclean is dangerous. I would not recommend removing packages if you do not have to by a script

depclean removes anything which is not related to the world file, and the world file itself, is a headache to keep it sane.

why not

emerge --sync; emerge --update --keep-going --deep -N world

you can add that bdeps things, but i hardly ever add that

i use

emerge --sync; emerge -av --update --keep-going --deep -N world

to see a list whats updated. that is also a decent point to uninstall software, change useflags, lookup useflags before you proceed.

--

also i would not recommend to use etc-update by a script. that tool is broken in my point of view. the majority are just fresh config files, where most of the time i delete rm /etc/.... _cfg_0000_file_name.
Never let a script touch the bootloader, grub.cfg or the /etc directory

etc-update will overwrite your network password, and other user changed config files, so you loose functionality. never ever use it carelessly! it's more recommended to ignore the message about config files

--

if you want to update your box and do not really care, add a cron job for that. not recommended but if you want to.

also setting kernel symlink, x-server + nvidia-driver can render you in loss of x-server, direct rendering, so an autoupdate script is not recommended.

gentoo has the habbit to provide kernels with not compatible nvidia-drivers. after 2 weeks you can update to a newer kernel branch usually after a new nvidia-driver is in the portage tree

it also does not remove older kernels, older kernel modules, cleans up boot.

--

i would not give the impression, that this update script fix everything for the newbie user. for the others its just enough to

emerge --sync; emerge -av --update --keep-going --deep -N world

Thanks for you feed back, I'll take a look at some of those things you listed. Never intended to give the impression that this is the script that fixes anything. If you read what I posted I state that I installed Gentoo and this is the script I use to update my system. This is an interactive script so nothing is done without your approval.

_roman_ · 12-03-2017, 05:26 AM

Honestly I just looked into your code, not in the text.

Thank you for your feedback.

I think my one liner is more than enough for that purpose.
