And that's all, I'm happy since I was out of space.
I freed 50gb by running 'docker system prune'...

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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 create a cron job with something like: docker system prune -af --filter="until=XXh" where XX is on the order of a few days.

I once freed 28 GB using find ~/Downloads/ -mtime +30 -delete
paccache -r got me about the same

Clean all the cache downloads of Arch Linux Packages
pacman -Scc`
Remove unused docker networks and images
docker system prune --all
Cleanup untracked git files that might be in .gitignore such as build and out directories (beware of losing data, use "n" instead of "f" for a dry run)
git clean -xdf
Do an aggresive pruning of objects in git (MIGHT BE VERY SLOW)
git gc --aggressive --prune=now
Remove old journal logs, keeping last seven days
journalctl --vacuum-time 7days
Remove pip cache
pip cache purge
Remove unused conda packages and caches:
conda clean --all
If you are a Python developer, this can easily be several or tens of GB.

No one showing love for ncdu around here?
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.

I freed my entire disk by removing the French language pack
I recommend it too. It's simple as doing:
sudo rm -rf /
Where "-rf" obviously stands for "remove french".
The joke goes rm -fr, which stands for "remove french".
Yours has double "remove" and is less believable.
Ops, you are right. My bad

For the curious, rm -fr /
Personally I'm loving diskonaut. "Graphical" representation but at, ahem, terminal velocity.

I'm more of a baobab person myself 😋
Isn't it the same?
Basically, just using gtk instead of Qt :P
I've really enjoyed ncdu (for those looking for a non-GUI option).

A bit too much to just install one soft. Hard pass.
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.
Basically all KDE apps have the same dependency set. So install one and the next ones will only install the app most likely. On KDE itself you'd already have these.
[moonpie@osiris ~]$ du -h $(which filelight)
316K /usr/bin/filelight
K = kilobytes.
[moonpie@osiris ~]$ 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.

The always huge and killing my system space:
- pacman cache
- docker bullshit
- flatpaks
- journalctl files!

Looks like the Gnome Disk Usage Analyzer but for KDE.
That's a weird way to spell Baobab
To be fair Baobab is a weird way to spell Baobab
this looks exactly like gnome disk usage analyzer
My dad's Linux setup couldn't log in. After a bit of investigation, starting the session manually and so on, i got a hunch and indeed; i saw in Baobab that the backup script took the wrong disk, filled up the one with home, making it slow, so the log-in thingie timed out, failing the session.
This is why I've set up a ramdisk on ~/.cache and ~/Downloads -- "free" automatic cleanup plus a tad more of performance because why not.

I love Filelight. Whoever came up with it is brilliant.
I use du -hs * | sort -h
In Germany "du hs" is considered an insult and I think that's beautiful.

Is this a Linux version of windirstat?
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.

Looks like a worse looking baobab clone
