Spartan only runs on the 10 SGI workstations in GITC 2315C. The workstations use the unix operating system. Log into your Engineering Computing (also called EC or afs) account using an SGI workstation. (Press the mouse button to get the login prompt.) There is a window that has TOOLCHEST, DESKTOP, etc. Choose DESKTOP & OPEN UNIX SHELL. A window will open & there will be a "%" prompt. Type "spartan" (unix is case sensitive, so use lower case). The cursor must be in the window, otherwise the typing will not appear and the command will not be executed. The SPARTAN window opens & you can use the menus to do the experiments. When you are done with SPARTAN, logout by choosing QUIT from the SPARTAN file menu. This puts you back in the unix window. You must then logout of the workstation, otherwise the next person who uses the machine will be in your account. To do that: (1) logout of the unix window by typing "logout", (2) Choose logout from the DESKTOP menu & answer "yes" to the question: "Do you really want to logout?"

Organization of files: You will be creating many files for each experiment and for your project. You will want to save them in separate folders (called directories in the unix OS). You can do this within Spartan when you go to save each file. But here are some useful unix commands (A basic unix tutorial is on the EC web site):

To make subdirectories, type mkdir <directory name>. For example, mkdir expt11

Type: cd expt11 (i.e. change directory), to go to that dir.

Type: ls —l to list the files in that directory.

Type: cd .. to go back to the higher level directory. If you get lost, type: pwd (i.e. present working directory) to locate where you are.

To read a file: cat <short file name> or man <long file name>

To copy a file: cp <source file> <destination file>

To delete a file: rm <file name>

To delete a file in a directory: rm <dir name>/<file name>
