Dust is a rewrite of du (in rust obviously) that visualizes your directory tree and what percentage each file takes up. But it only prints as many files fit in your terminal height, so you see only the largest files. It’s been a better experience that du, which isn’t always easy to navigate to find big files (or atleast I’m not good at it.)
Anyway, found a log file at .local/state/nvim/log that was 70gb. I deleted it. Hope it doesn’t bite me. Been pushing around 95% of disk space for a while so this was a huge win 👍

I think something might be wrong with your Neovim if it aggregated 70 gigs of log files.
don’t worry, they’ve just been using neovim for 700 years, it’ll be alright
So I found out that qbittorrent generates errors in a log whenever it tries to write to a disk that is full…
Everytime my disk was full I would clear out some old torrents, then all the pending log entries would write and the disk would be full again. The log was well over 50gb by the time I figured out that i’m an idiot. Hooray for having dedicated machines.
I once did something even dumber. When I was new to Linux and the CLI, I added a recursive line to my shell config that would add it self to the shell config. So I pretty much had exponential growth of my shell config and my shell would take ~20 seconds to start up before I found the broken code snippet.
Try
ncduas well. No instructions needed, just runncdu /path/to/your/directory.I usually use something like
du -sh * | sort -hr | less, so you don’t need to install anything on your machine.Almost the same here. Well,
du -shc *|sort -hrI admin around three hundred linux servers and this is one of my most common tasks - although I use -shc as I like the total too, and don’t bother with less as it’s only the biggest files and dirs that I’m interested in and they show up last, so no need to scrollback.
When managing a lot of servers, the storage requirements when installing extra software is never trivial. (Although our storage does do very clever compression and it might recognise the duplication of the file even across many vm filesystems, I’m never quite sure that works as advertised on small files)

What do you use for management? Ansible? Puppet? Chef? Something else entirely?
Main tool is Uyuni, but we use Ansible and AWX for building new vms, and adhoc ansible for some changes.
Interesting; I hadn’t heard of Uyuni before. Thanks for the info!
Seems it just runs Salt/Saltstack?
Suse forked Redhat’s Spacewalk just before it turned into Foreman + Katello.
Then worked an absolute crapload on it to turn it into a modern orchestrator. Part of that was to adopt salt as the agent interface, gradually getting rid of the creaking EL traditional client.
To say “it just runs salt” is to rather miss all the other stuff Uyuni does. Full repo and patch management, remote control, config management, builds, ansible playbook support, salt support, and just about everything else you need to manage hundreds of machines. Oh, and it does that for Rocky, RHEL, Alma, Suse, Ubuntu, Debian and probably a bunch more too, by now. Has a very rich webui, a full API and you can do a bunch more from the cli as well. And if your estate gets too big to manage with one machine, there are proxy agents, as many as you want. I only run a couple of hundred vms through it, but there are estates running thousands.
And it’s free and foss.
Honestly, it’s pretty awesome and I’m amazed it’s not more widely known.
Oh that’s pretty nifty, thanks for the comment. Sorry wasn’t trying to minimize the tool, I was simply referring to the orchestration/config management aspect of it when I looked it up real quick.
I used to be responsible for configurations of 40,000 (yes forty thousand) VMs for a large company using puppet and then later using Ansible and that was an interesting challenge. I’ve been out of the configuration management game for a few years now though so I’m pretty out of the loop. Was familiar with spacewalk back in the day too.
I’ll have to check Uyuni out, thanks for sharing!
ncdu is the best utility for this type of thing. I use it all the time.
Try dua. It’s like ncdu but uses multiple threads so it’s a lot faster., especially on SSDs.

What about the video similarity finding tool built into Czkawka? Is it not as good as VDF?
