> I rushed to run du -sh on everything I could, as that’s as good as I could manage.

I recently came across gdu (1) and have installed/used it on every machine since then.

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

I can't recommend `dust` enough: https://github.com/bootandy/dust

I have an alias named usage with this in it:

    du -hs -- * .??* 2> /dev/null |  sort -h | tail -$LINES

Have you used ncdu? I wonder how this compares.

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

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.
