I freed 30GB using Filelight

last year I had over 1TB freed by docker system prune on a dev VM. If you're building images often, that's a mandatory command to run once in a while.

I once freed 28 GB using find ~/Downloads/ -mtime +30 -delete

paccache -r got me about the same

I'm new to docker and all of my shit stopped working recently. Just wouldn't load. Took about a half hour to find out that old images were taking up about 63GB on my 100GB boot partition, resulting in it being completely full.

I added the command to prune 3 month old images to my update scripts.

Oh hey thanks for reminding me, freed 5GB which should buy me a bit of time on upgrading the server I use for this lemmy instance.

Oh, that reminds me,...

Remove unused conda packages and caches:

conda clean --all

If you are a Python developer, this can easily be several or tens of GB.

I can see you're not using Flatpak, the destroyer of disk space. Nice list though!

Ncdu is my go-to tool. Can't live without it on the servers I administer. However from this thread I've also learned about gdu, diskonaut and du-dust that I need to check out.

Goat

I recommend it too. It's simple as doing:

 undefined

    
sudo rm -rf /

  

Where "-rf" obviously stands for "remove french".

For the curious, rm -fr /

Jesus, that rustup folder is HUGE

I use dua, but this looks neat too.

Linky pls

Isn't it the same?

In case you don't already know about it, paccache (part of the pacman-contrib package) will let you easily remove old packages from the pacman cache

That's very normal if you don't have any KDE apps. If you were using KDE and installed a GNOME app it'd be similar.

It's a KDE application, yes.

Looks like the depends list of the average KDE app on a none KDE system.

You could try baobab instead.

Lol I had no idea it relied on so much. Its just built into KDE. Really great app overall.

 undefined

    
[moonpie@osiris ~]$ du -h $(which filelight)
316K    /usr/bin/filelight

  

K = kilobytes.

 undefined

    
[moonpie@osiris ~]$ pacman -Ql filelight | awk '{print $2}' | xargs du | awk '{print $1}' | paste -sd+ | bc
45347740

  

45347740 bytes is 43.247 megabytes. That is to say, the entire install of filelight is only 43 megabytes.

KDE packages have many dependencies, which cause the packages themselves to be extremely tiny. By sharing a ton of code via libraries, they save a lot of space.

My little widget to get the weather, Blazing Fast Uber Duper made in Rust, has like 85 total dependencies from like 3 crates that I need...

My own software is a hard pass for myself...

That's great!

Another thing that is great, since we are talking about disk space: people, check your Rust repositiry, it might be huge.

I deleted that folder and, in my case, freed 12gb. Not too shabby.

On gtk desktops it's something like Baobab. Too sad that the big guys can't make lightweight and standalone software.

flatpak install flathub org.kde.filelight

That's a weird way to spell Baobab

Came to recommend du-dust!

Isn't that a wayland notification daemon already?

Edit: no, that's dunst.

Btw, how do you do the background color thing?

I have to remember to check this out. its on my reminders in my self host calendar but its been offline fpr quite some time after moving.

Also dust

I'm à qdirstat guy : https://github.com/shundhammer/qdirstat

I might do that just to force myself to organize and move files out of downloads.

In Germany "du hs" is considered an insult and I think that's beautiful.

This tool is amazing https://github.com/KSXGitHub/parallel-disk-usage

duf is pretty slick

If you need a more interactive method, gdu is awesome. And if you're using btrfs, btdu gives preliminary results instantly (which get more precise over time).

du -sxk | sort -n gotta find those hidden files too!

There's also QDirStat which is like KDirStat but without KDE dependencies.

There's a more direct version of that, I guess from KDE, called KdirStat.

I hadn't heard of the one in the op. But if I had to guess, it looks like it's a different take on the same idea.

side note: wiztree performs better on windows than windirstat, radically faster scans

now I feel dirty talking about windows here..

Filelight is about finding the folders you don't use that take a lot of space. Basically an easier way to look into which folder takes up what.

Fclones is a great tool, but it's for finding duplicate files and replacing them with sym-/hard-/reflinks.

I recommend using the --cache option to make subsequent runs extremely quick.

These tools are also useful for finding large files in your home directory. E.g. I've found a large amount of Linux ISOs I didn't need anymore.

No, and I miss it. Space sniffer was so good.

Nah, in a rolling distro it's normal, they were mostly unused stuff hide in /home, and useless yay pkg.

Sir, this is not Windows.

Do you delete all your files on a reinstall? Documents, photos, videos, games?
