Clean up usr/lib

shmu26 · 21 December 2023 11:00

My usr directory is taking up more than 13 Gb and most of it is in /lib and /share
I am puzzled why it is so big. Any ideas how to thin it out?

I have noticed sometimes old modules are left around in /lib

If you would like to run this script:

#!/usr/bin/env bash
#
# gcspt
#
# grub+ configuration search presentation tool
#
# <3 cscs <3
#

gcspt=$(find /boot -type f -name '*.cfg' 2>/dev/null | sort);
gscpt=$(find /etc/grub.d -type f ! -name 'README' 2>/dev/null | sort);
initz=$(find /boot -type f -name 'initramfs*' 2>/dev/null | sort); 
imgz=$(find /boot -type f -name 'vmlinuz*' 2>/dev/null | sort); 
modz=$(find /lib/modules -maxdepth 1 -type d 2>/dev/null | sort);
mkinitz=$(find /etc -type f -name 'mkinitcpio*' 2>/dev/null | sort); 
mkinitzd=$(find /etc/mkinitcpio.d -type f 2>/dev/null | sort);
dracutz=$(find /etc -type f -name 'dracut*' 2>/dev/null | sort); 
dracutzd=$(find /etc/dracut.conf.d -type f 2>/dev/null | sort);

_gcspt_format () {
    while read in; do ls -l --time-style=+'%F %R' "$in" | cut --complement -d ' ' -f1,2,3,4,5; done | column -t
}

#printf '\n...Bite-Sized Boot-Info...\n';

printf "\nCurrently Running Kernel:\n$(uname -s -r)\n";

printf '\nGrub Configuration Files:\n';

echo "$gcspt" | _gcspt_format;
echo "$gscpt" | _gcspt_format;

printf '\nInstalled Kernels:\n';

echo "$imgz" | _gcspt_format;

printf '\nInitramfs Images:\n'; 

echo "$initz" | _gcspt_format;

if which mkinitcpio >/dev/null 2>&1; then

printf '\nmkinitcpio:\n';

echo "$mkinitz" | _gcspt_format;
echo "$mkinitzd" | _gcspt_format;
fi

if which dracut >/dev/null 2>&1; then

printf '\ndracut:\n';

echo "$dracutz" | _gcspt_format;
echo "$dracutzd" | _gcspt_format;

fi

printf '\nModule Directories:\n'; 

for i in $modz; do du --time --time-style=+'%F %R' -sh $i; done | awk '{print $2,$3,$4,$1}' | column -t; 

printf '\nHibernation:\n';

grep -o 'resume=' /etc/default/grub || printf 'No "resume=" option found in /etc/default/grub\n';

printf '\nSettings of /etc/default/grub:\n';

awk 'NF && !/^ *#/ { print; }' /etc/default/grub;

printf "\n"
exit

(save as a file name gcspt, mark it executable with chmod +x gcspt, then run with ./gcspt)

And then also return

mhwd-kernel -li

We might see what directories are expendable.

soundofthunder · 21 December 2023 11:08

This might give a better appreciation of space used:

pacman -Qqe > pkglist.txt

It lists all installed packages, and writes them to ‘pkglist.txt’ in your home directory. I hope this helps to an extent.

I found TeX Live, as an example, filled to 6/7GB initially (using a reduced version now).

It gives you a list in alphabetical order, but it doesn’t tell the size of the packages.

soundofthunder · 21 December 2023 11:31

No, but it reminds you of the number of packages you have installed.

The package sizes are of no real consequence, as they are extracted during install taking up an even greater amount of space.

I don’t recall the exact command that might also include package sizes, but I’ll check for you. OK, I’ve found no pacman command that does that, as expected, but these may help as you continue your quest:

To list all packages no longer required as dependencies (orphans):

pacman -Qdt

To list all packages explicitly installed and not required as dependencies:

pacman -Qet

These come from Pacman in the ArchWiki.

xabbu · 21 December 2023 11:37

This command lists packages by size.

expac -s "%-30n %m" | sort -rhk 2 | less

You might need to install expac first.

shmu26 · 21 December 2023 11:48

I did that one and in Konsole I see like below, but I can’t figure out how to navigate the output

xabbu · 21 December 2023 11:50

Maybe try

expac -s "%-30n %m"

first to see if there is anything returned.

soundofthunder · 21 December 2023 11:54

Or, this:

expac -s "%-30n %m" > ~/pkglist_with_sizes.txt

Then check your user directory for the resulting file.
It’s sorted alphabetically by default.

The OP can probably delete that (mainly empty and useless) preformatted text box in the previous post.

shmu26 · 21 December 2023 12:12

Thanks, that actually turned up some interesting stuff that I will need to research if I still need those packages.

soundofthunder · 21 December 2023 12:20

Try to focus on packages you know you installed, and avoid those you’re initially unfamiliar with. Some of them you can simply uninstall if not needed. Of those you do uninstall, check for folders under ~/.config etc., that are related to them, and remove those also. Good luck.

This might give you an idea about locales
