I have a user that really like to create files. Then, they don't clean them up. We have already put a quota* on them, but unfortunetly, their directory is so large and convaluted, that they can't even figure out where all the disk space has gone. Is there a sane way to generate a report showing the disk usage from a certain point on down, sorted by size? Heres kinda what I mean: for a standard user, I would just run 'du /u/foo | sort -n | tail -20', and tell them to clean up whatever is there. However, I've let a du | sort -n run on this directory for over four hours, before giving up in disgust. It is almost 100Gigs of files, with at least four or five directories that have 20K to 30K+ files each (plus hundreds of other subdirs). *And*, it's on a filer, so there are .snapshot directories that du thinks it has to plow through, quintupling the amount of work. I'd also like to make this into a weekly report, so that they can make it part of their Friday routine (let's go delete 10 gigs of data! Woohoo!).
Ideas? Other than killing them, of course, no matter how tempting that is...
Maybe use find and restrict the search depth to at least find some large dirs, plus exclude the snapshots? Sth like "find /where/ever -size +10000k" for the larger files, and for large dirs maybe, haven't tried, "... -size +1k - type d". If you pipe this through awk you can easily sum it up.
I remember once writing a script to reporting disk usage on a web server above the purchased amount.
Cheers, Marcel
