Diistinctly not true. `nix run github:nixos/nixpkgs/nixos-unstable#dua`

Actually it is in the arch community repositories and seems to be quiet a bit faster than ncdu so I will keep it in my toolbox for now.

Painpoints are that there seems to be no progress bar in interactive mode, the ui is (imho) ugly/unintuitive (for instance the usage bar seems to be relative? and the shortcuts look like glyphs) and there are functions missing (like exclude patterns, you can exclude dirs though!).

So it won't replace ncdu, but if it get a interactive progressbar maybe it will be on all my machines (with arch)

/usr/ports/sysutils/dua-cli

it's in the void and arch repos
