Tactile Interrogator for Mac

Tactile Interrogator is the first graphical command shell designed for power users, providing a rich graphical file view of Mac OS X's powerful Unix underpinnings, in addition to the usual Mac OS information. Although similar to the Finder, it uses colored icons, in different sizes, to give the Mac user an informative picture of a directory at a glance, highlighting recent changes, excessive disk consumption, or unprotected files, even if buried subdirectories below.

Detailed information displays include all five different file dates, all four status words, descriptions of each file in a chain of symlinks or aliases, and aggregates over directory contents - not just size, but earliest and latest dates, most and least restrictive permissions, and deepest and widest subdirectories. Information is cached for rapid access, and there are keystrokes for most operations.
