Hard drive mysteriously full

How can I identify what file(s) are causing my disk to be at 100% usage?

Well, there's a variety of ways to do that -- one would be to simply go into /, and run "du -sh *".

Then, head towards the directories that are using the most amount of space, and then do the same thing again.

You'll eventually reach the files/directories that are using a lot of space.

That did it! Thank you!

I forgot I had done a big grep > output.txt

The output.txt was over 200GB! I feel dumb again ;-)
