Today I discovered ncdu while trying to find a script that would display all files on a Linux system sorted by size.

ncdu is Absolutely Amazing!

When you first run ncdu, it scans the current directory and any sub directories and calculates disk space used. It then sorts the output so you can easily find files that are the largest and taking up the most space.

Here is what it looks like when run under the /var/lib directory:

Navigating further into /var/lib/libvirt/images shows the individual files sorted by size.
