Small bash script to push list of installed packages to github repo

On the wiki I saw that I should consider holding list of installed packages in case of disaster: wiki page
And so I created small script to push list of packages to my github, I plan to put it to cron
Maybe someone will find it helpful.
Also, I am not good with bash so I am open for suggestion

#!/usr/bin/bash
cd ~
git clone https://PERSONAL-ACCESS-TOKEN@github.com/USER/REPO
cd REPO
git pull origin main

FILE_NAME=$(date +"pkg-list-%Y.%m.%d-%T")

touch ./lists/$FILE_NAME.txt
yay -Qqe >> ./lists/$FILE_NAME.txt

FILE_COUNT=$(ls -1 ./lists | wc -l)
if [ $FILE_COUNT -gt 1200 ]; then
        OLDEST_FILE=$(ls -1tr ./lists | head -n 1)
        rm ./lists/$OLDEST_FILE
fi

git add .
git commit -m "Auto-commit: Package list on $FILE_NAME"
git push -u origin main

I wonder if making backup of other things will be beneficial, maybe /etc or ~/.*

Re: Small bash script to push list of installed packages to github repo

Hi, a backup of all your data will be beneficial in case of a disaster :-)

To minimize the data volume, you could make 3 batches of prio:
prio1 data : e.g. important personal files, emails, backup every day
prio2 data : e.g. program settings, once a week
prio3 data : backup the whole hard-disk including operating system, once a month

Line out your personal backup strategy, deploy it, use it regular, test the theoretical disaster case : could you read and restore all data ?

Do not use yay, especially when there is no need to use it. pacman is your package manager and gives you a list of installed packages.

Re: Small bash script to push list of installed packages to github repo

That script makes no sense. Why not just use a single file containing the package list and over-write it every time? Git itself will keep track of the old files anyway.

Note that parsing ls is generally a bad idea, although it won't cause problems in this particular example.

EDIT: just for the record: you can place the files in an array to count them:

files=(.list/*)
echo "${#files[@]}" # returns number of files

Determining the oldest without parsing ls is trickier though, perhaps try something like the `stat` suggestions here.
