Most sysadmin will run low on disk space. Users will demand more space and you need to free space. You will find out files that???s a waste of space and delete it or move to an archive medium. But, how do you find the right files to delete that can help recover maximum space? Say hello to agedu tool (pronounced as ???age dee you???) ??? it 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, this command might help you to free up disk space.
