It lays out the directories in a hierarchy with each directory represented by a pedestal. The height of the pedestal is proportional to the size of the files in the directory. The directories are connected by wires, on which it is possible to travel. On top of each directory are boxes representing individual files. The height of the box represents the size of the file, while the color represents the age. Fsn was written several years ago by myself and Steve Strasnick, as an investigation in information landscape navigation. It was the progenetor of the current Tree Visualizer in the Silicon Graphics MineSet(TM) product. Fsn was featured in the movie Jurassic Park. Keep in mind that fsn is a prototype and an experiment. It is neither a full featured product nor a replacement for a filesystem manager such as Indigo Magic. Fsn requires Z-buffering and RGB support. You must be running IRIX release 4.0.1 or greater. There are two files available. fsn.tar.Z should be used if you are running IRIX 5.3, 6.2, or later. fsn.COFF.tar.Z should be used for earlier releases. (fsn.tar.Z might work for prior 5.X releases, but has not been tested.) The file fsn.tar.Z can be uncompressed using the command: uncompress < fsn.tar.Z | tar xvf - It will produce the following files: fsn: The file system navigator fsn.z: the compressed man page Fsn: The app-defaults file Fsn.icon: A window manager icon Makefile: used to install the files Fsn can be run as is after unpacking, or to install all of the files, su, and run "make install". Fsn should be invoked with a parameter specifying the top directory to be looked at. This directory can be "/", in which case the whole file system is scanned. Although the system works fine starting at "/", startup time is somewhat longer, and movement can be chunky if you have more than about 1500 directories. You may prefer to start at your home directory. Even if you start at "/", you can still prune it to a small size using the Prune function. After pruning you will need to restart fsn to reclaim the memory. When scanning a file system, fsn will not cross file system type boundaries. For example, it will not cross into an NFS file system. However, it will cross mount points of the same type of file system. The first time fsn is run it will scan the whole file system. Be patient, this can take a few minutes. After it has scanned the file system it will save a database in your home directory so that subsequent startups can be done in seconds rather than minutes. On subsequent runs the database will be read, making fsn quickly available. Using fsn is easy. The manual page goes into a lot of detail, but here is a quick overview. The left mouse can be used to select directories and files. Clicking on a directory or file will select it and zoom in. Double click with the left mouse will execute or view a file, and "Warp" into a directory, where there is a different viewing paradigm. The middle mouse can be used to navigate. While holding down the middle button, move the mouse in the direction you want to go. The farther you move the mouse from where you clicked, the faster you go. Shift-middle mouse also moves you up and down while moving forward and backward. The right mouse pops up the file menu, which can also be found on the menu bar. There is also an overview window (which can be hidden if you don't want it). This window shows you all the directories, and where you are. You can also use it to select (left mouse), or move (middle mouse). You may also want to experiment with the landscapes. The landscapes control the colors of sky and ground, and can be selected with the -landscape option. Be aware that the landscapes that use Gouraud shading will not look all that good on an Indigo.
