Welcome to the duf home page.

duf is a tool for analyzing where space is being used in a UNIX directory hierarchy. It actually reformats and reorders the output from the standard UNIX du utility into a more readable and useful format. Also, various options are supported.

An article about duf entitled ``Toolman Visualizes Disk Usage'' appears in the August 1997 issue of the USENIX Association's ;login: magazine.
