KDE has some way to display the disk usage way quicker than a du -sh / would do. Probably with caching etc.
Set aside transparent BTRFS compression (not sure if that is calculated in), it is really useful.
is there a way to call for that tool to display the disk usage from the CLI?
I use Filelight
yes but I meant a command, like in a script for example. maybe something using qdbus
it might need to interact with kio or other libraries using C++? There is likely no interface or tool exposed to users
the idea is that when scripting in a desktop environment, it is way more efficient to just get the already collected stats from there, instead of using some ancient unix method to do it again
LLMs suggest a mix of find and stat, which takes forever. Or there is du, which scans everything new, no caching, no index etc.
I use baloo but not on all files. that might be a tool with such an interface exposed, but maybe not either?
Maybe you’re looking for df -hl?
yes, somehow that is instant where du takes a long time!
solves my use case, thanks!
