Ncdu – NCurses Disk Usage

If you use a Btrfs filesystem with snapshots, I can recommend Btdu as an alternative. Advantage: Can handle duplicate files (snapshots), which however only occupy 1x disk space.

More interesting than its support of Btrfs features is its unusual statistical approach:

> btdu is a sampling disk usage profiler […] Pick a random point on the disk then find what is located at that point […] btdu starts showing results instantly. Though wildly inaccurate at first, they become progressively more accurate the longer btdu is allowed to run.

At first blush, this beats the tar out of using other deduplicator strategies on btrfs. I'm looking forward to checking this out more thoroughly.

This looks very useful! I wish there were something similar for ZFS.

Have used btdu - very useful on Btrfs systems with lots of snapshots.
