"I played with cron once so it may have consumed my mass memory, but really I have no clue."
No clue, you say? never would have guessed. :)
du -s ./* | sort -n
"du" shows disk usage, in blocks (1 block = 0.5 kilobytes, in all cases that matter to you.)
-s means, "summary", so it gives only a total for each argument "./*" being the argument.
piping it into sort -n means sort numerically. The larger numbers at the bottom.
So, you'll get a list of directories with the ones using the most space at the bottom.
If that's not enough help, say you get:
and you see that ./home is the biggest piggy,
ok, cd into /home, and do the same "du -s | sort -n" Then you see who in /home is taking up space. (on a single user system, well, it's probably you.)
Then cd into there, and do "du -s | sort -n" again.
Keep doing this until you find the culprit. When you find the culprit, you may say, oh yeah... that's my collection of hi-res renderings of Romulan Birds of Prey for my star trek RPG game that I'm building, so yeah, of course that takes up a lot of space, or you may say, of course that takes up a lot of space, so let's rm -fr that bad boy.
Magic words to remember:
du -s | sort -n
