Agedu – A Unix utility for tracking down wasted disk space

agedu scans a directory tree and produces reports about how much disk space is used in each directory and subdirectory, and also how that usage of disk space corresponds to files with last-access times a long time ago. In other words, agedu is a tool you might use to help you free up disk space. It lets you see which directories are taking up the most space, as du does; but unlike du, it also distinguishes between large collections of data which are still in use and ones which have not been accessed in months or years – for instance, large archives downloaded, unpacked, used once, and never cleaned up. Where du helps you find what’s using your disk space, agedu helps you find what’s wasting your disk space. Full Story
