What's been eating my disk ?

I'm sure I've posted this before, but repetition is the most sincere form of .... something deep and meaningful.

Want to see what's eating your disk in a particular file-system ?

Try: -

du -hs * | sort -h

against, say, /home to see who is eating your disk, especially in terms of specific user's home directories etc.

That is a great idea if you cannot install other tools.
But there is actually a simple and nice tool called "ncdu".

It's part of epel in RHEL/CentOS.

ncdu gives you a list you can navigate :-)

Thanks for this. Will see whether that exists on Ubuntu as well.

Cheers. Dave
