PSA: Remember to also check hidden directories you don't even know about for waste of space

Apparently, Prism Launcher chose to adhere to the idiotic principle of the hidden “trashbin”, .Trash-$(uid), invented by Ubuntu. Even though it’s based on QT. This can’t be disabled. It accumulated 139 GB of literal Trash, fully replaceable, over time. Just … why? There’s even an open issue about this, for over a year, referenced multiple times. I guess I have another point on my agenda.

I did this yesterday while trying to make a backup before formatting and then updating my work rig and I’m SO GLAD that the decades have taught me to take knee-jerk/automatic actions that forces me to make entire volume backups; otherwise this last month of work life would have been AWFUL!!!
You can easily set it up to do this automatically with something like timeshift…
I recently switched to an Atomic distro (Bazzite), and they have made it so easy to rollback to previous commits without any additional software.
I use rsync on a cron job and it do it automatically every time i add a new drive or volume.
This isn’t some “idiotic principle invented by Ubuntu”, it just follows the freedesktop.org Trash specification. For many users, it can be really beneficial, see also the spec’s introduction:
Whether an application like Prism Launcher should use the trash can or delete the files directly is an entirely different question.
But why wouldn’t they use .local/share/Trash instead? Isn’t that supposed to be a unified directory for that very purpose?
Because that would take a long time if you deleted a large file in another partition or drive. You could also end up not having enough space to move the file to trash and if the trash directory is on an SSD, it would add a lot of unnecessary wear to it.
To explain it a bit further: when you move a file/directory on the same mount point, moving the file/directory is essentially just a rename operation, which doesn’t involve copying the data itself and is a very cheap operation. If you move a file/directory across mount points, you need to (recursively) copy the file/directory, copy file metadata and (recursively) delete the old file/directory, which is slow and error-prone.
and proper trashing is actually really helpful, so you can trash files on encrypted volumes without leaking them to a unencrypted trash dir.
trashing saves time and has a more continous workflow, as you don’t have to confirm each file to prevent accidents, because you can restore if you deleted too much
So an idiotic spec invented by freedesktop then
Hard delete used to be in the drop-down along with move to Trash, since I rarely accidentally delete things and when I do I have backups, I much preferred that arrangement.
Depending on your file manager, you may be able to hold Shift while triggering the delete to get a hard delete.
Shift+Del is pretty much standardized as the keyboard shortcut. And here on KDE, I can hold Shift while clicking the “Move to Trash” menu entry, too (well, it actually replaces the menu entry with one for permanent deletion, but that’s effectively the same).
Shift-del
@troyunrau In mate it's a drop down menu not a key.
I don’t use mate, but assuming that it has a file manager and that file manager has hotkeys that conform to the muscle memory that is built using other file managers… Try it and see what happens?
@troyunrau Ok did try, delete + center button mouse click does remove the file however since the only delete on my keyboard is right side and I'm right handed handed and and thus also use the mouse right hand, not terribly useful.
Well, that’s on mate then. In KDE you could remap to a combo of your choice with ease
@troyunrau KDE wastes too much screen space and too much of my time. It's pretty but inefficient.
All I’m hearing is complaining. It’s open source. Fix mate then so it does what you want.
@troyunrau Not complaining, just explaining my choice for a particular desktop and preferences. I realize it's open source and I realize I have the source so if it's severe enough I have the option of modifying it. If only I had infinite time.
This is why I use gdu on servers
On servers I primarily use a terminal, only for things like virt-manager do I ever fire up a desktop so on servers mostly moot.
I use command
trash-emptyto empty all trashcan of all the users, after each system update. It’s a non standard program, but most likely available in your distributions repository: github.com/andreafrancia/trash-cli And my alias/function will show each file that is about being deleted (just put it in .bashrc, if you have installedtrash-cli, which includestrash-empty):old function (click to expand)
empty() { echo “Files to delete:” trash-empty -f --dry-run | awk ‘{print $3}’ | grep -vF ‘/info/’ echo trash-empty }Edit: After I posted I just realized there is a more straightforward way of doing it:
New and more simple alias:
This searches all trash cans, lists all files it has found to be deleted, then lists all directories it looked under and then asks if you want really delete. With
trash-empty -fit deletes without asking.Your desktop environment should have settings for when to clear the trash. You can also use autotrash to clear it automatically.
The Problem is: I don’t have a DE, and therefore didn’t realize programs would still try to use trashbins.
Doesn’t people use a disk usage scanner every once in a while to find out if there’s something hogging space?
I do, except I always used du -hs *, which does not include hidden (.-Prefixed) files. So a double trap.
shopt -s dotglobwill make*include .dotfiles.If you have 4 TB disk, you don’t care until it is getting full.
I have several 4 and 8 TB disks filled up with various stuff just waiting to be cleaned up. Why do you think I’m preaching about storage space management?
My dual 10’s are starting to fill up because I don’t move stuff off-site as I should. And then reclaiming space through disk analyser and freeing up reserved space is a life saver.
I do, because it is the same with a 4 TB disk and 100 GB games as it is with a 256 GB disk and png’s & office stuff.
I use ncdu. It shows what folders/files are actually eating up all your space.
I was about to suggest this. It comes with a nice TUI that sorts by highest disk usage.
Neat! I kept using du and df and work my way to the culprit. On PC’s with GNOME I use baobab.
All .Trash-1000 files appears in your trashbin no? At least is how is working for me.
Isn’t it common that file managers have a trash bin? Thunar does.
ncduI’m more of a dust man, myself. It runs recursively so it’s easy to pinpoint the culprit.
