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 :-)

    Hi Daniel

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

    Cheers. Dave
