Task Zero (logon to the Xterm)

Your class account is set up with an "Xterm" window, a minimized "Xterm" windows, and two clocks. The Xterm window has the prompt rohan.mascXXXX, where mascXXXX is your class account. The minimized Xterm window can be activated by double clicking (with the left mouse button) on its Icon.

Task One (a little UNIX) Perform this task in an Xterm Window

Change your password:

In an Xterm Window at the UNIX prompt, type
passwd
You will be asked for your current password and then asked for the new one. It should be at least 6 characters long and include at least onek upper case letter (A-Z), digit (0-9) or punctuation character (such as . , or -). It should not be a word easily found in the dictionary.

Change your finger:

In an Xterm Window at the UNIX prmopot, type
chfn
and change your identity to the system from being "Generic Account" to be your name.

Task Two using Netscape Navigator

1. Set the home page to be rohan (Options/Preferences/Window and Link Styles - fill in http://rohan.sdsu.edu
2. Open the location for this courses notes (File/Open Location) http://www.stewart.cs.sdsu.edu/cs205/
3. Save this link as a bookmark (see toolbar for Bookmarks)
   

   (updated) Task Three [using pine] - start in an Xterm window

   • Use pine send mail to stewart by typing
     
     pine
     
     and filling in the "blanks". Your To: field will be stewart.
   • There were difficulties in lab because pine requires that the first time it is used, it be invoke by the just typing pine so that the program can set up folders for you automatically. Our original lab notes directed you to type pine stewart which confused the pine program.

     It is required that you use cs205 as the first phrase in your subject field on any email you send to me, the instructor

     pine will have to initialize itself the first time you use it, so watch the messages at the bottom of your screen and accept all the defaults. In the body of the mail message, please send me a simple note so that I can check that your identity has been changed by performing Task 1 above.

   
   

   Task Four- Using MATLAB

   
   
   1. In a Xwindow, start up MATLAB by typing
      matlab

      at the UNIX prompt. You should have both the Netscape Navigator and MATLAB running at the same time in two different windows. Experiment with dragging the mouse across your screen and seeing how the colors change.

   2. Within MATLAB, type
      demo205

      at the MATLAB prompt >>

   This will be our introduction to the "language" of MATLAB.
