I also discovered gdu recently. It's really good. It saves me running du -h --max-depth=1 | sort -h a million times trying to find where the space has gone while you're stressing about production being down.

gdu is really nice but ncdu, though slower, is very useful and is usually available on distro repos.

I use dust for this, but gdu looks nice, I'll give it a try. Thanks for sharing.

Have you used ncdu? I wonder how this compares.
