[OSX-Users] Re: scroll back buffers?Re: lion -or something - eating gigs?

Tue Jan 3 15:47:24 GMT 2012

My tried-and-tested Unix method for finding runaway files is to run 'du -ks * | sort -n' in / as root and see which subdirectory is the largest, then cd into it and re-run the command until I find out where all my disk space has gone. It's not very useful if you've lost it all to millions of little files, but it's good for finding multi-gigabyte files that you weren't aware of or had forgotten about.

Regards,
