ncdu - a ncurses based du | cli.pignat.org

ncdu is a console (ncurses based) disk usage analyser, like baobab for Gnome or windirstat for Win*, looking like this:

du (or ncdu) and df may not agree on disk usage, see also df vs du - where my free disk space is gone?.

Danger ncdu (by default) can delete files, so I highly recommend to disable that feature.

Safe configuration for `ncdu` version >= 1.19 (tested on 24.04)

ncdu, starting from version 1.19 can be configured in files /etc/ncdu.conf and $HOME/.config/ncdu/config.

Example configuration file:

# @file ncdu.conf
# @author marc@pignat.org

# make ncdu read-only
# -rr does the same
--disable-delete
--disable-shell

If you use the global /etc/ncdu.conf, make sure it is world-readable :

sudo chmod a+r /etc/profile.d/00-ncdu-readonly.sh

Create the world-readable file /etc/profile.d/00-ncdu-readonly.sh
```
alias ncdu='ncdu -rr
```

OR run this script:

echo alias ncdu=\'ncdu -rr\' | sudo tee /etc/profile.d/00-ncdu-readonly.sh
sudo chmod a+r /etc/profile.d/00-ncdu-readonly.sh
