2 Readings, Assignments, Labs, Tests, and ToDo

2.1 Read (at least) these things (All The Words)

  1. Week 11 Notes HTML – this file – Read All The Words
  2. Shell Control Structures – if, then, else, test, [...]
  3. Shell Script Problems – arithmetic, syntax, test, boolean, etc.
  4. List of Commands You Should Know
  5. Linux and Sysadmin News in the World
  6. Video Tutorials on Lynda.com – tagged by week number

2.2 Assignments, Quizzes, and Lab work this week

Reminder: There are now two quizzes that you need to complete on Blackboard as part of your term Quiz mark. A third quiz will be posted before the Final Exam. The Quizzes are not optional; see the Course Outline.

Check the due date for each assignment and put a reminder in your agenda, calendar, and digital assistant. Just like in the Real World, not all due dates are on the same days or at the same times.

2.3 Worksheets

Worksheets are preparation for your assignments. You can’t do the assignments without having done the worksheets first, and you can’t do the worksheets without having first read the Course Notes:

  1. Read the web notes. (Please: Read All The Words)
  2. Do the relevant Worksheet(s).
  3. Do the relevant Assignment(s).

Form a small study group to do the worksheets. Each person tries the example given, and you make sure you all get the same answers. Worksheets are not for hand-in; they are not worth marks; the assignments test your knowledge of the lectures and worksheets.

The worksheets are available in four formats: Open Office (ODT), PDF, HTML, and Text. Only the Open Office format allows you “fill in the blanks” in the worksheet. The PDF format looks good but doesn’t allow you to type into the blanks in the worksheet. The HTML format is crude but useful for quick for viewing online.

Do NOT open the Worksheet ODT files using any Microsoft products; they will mangle the format and mis-number the questions. Use the free Libre Office or Open Office programs to open these ODT documents. On campus, you can download Libre Office here.

Worksheets prepare you for the upcoming assignments.

2.4 Upcoming tests and exams

This course has two midterm tests and one final exam.

3 Notes from the Classroom

3.1 Commands Used

3.2 Finding world-writable files in your account

The assignment Checking Programs may issue this message:

Number of world-writable pathnames in abcd0001 account: 1
       ERROR: Sysadmin do not create files that anyone can overwrite.
       ERROR:       See "Examples of uses of find" to find these files.
   ERROR(-1): Fix the permissions on these files

Don’t create files or directories that anyone (“other”) can write, except the few required ones in the one Assignment #08 HTML head directory!

You must look at all the files in your account to try to find these files or directories that you have created with “other” write permissions. You can find the files the hard way, using cd and ls, or you can do it the easy way using a recursive command:

4 Class Web Site Photo Montage

As part of Assignment #08 HTML you created your own Student Web Site, for example: http://cst8207.idallen.ca/~cst8207b/

A clickable public montage of all the uploaded head-shot pictures is available at http://cst8207.idallen.ca/montage.cgi

You can still create or update your own web site on the CLS (please do!) and your image will be automatically added to the class photo montage.

This page is available to everyone on the open Internet. If you do not want your image shown on the montage page, follow the directions at the bottom of the page and then touch your photo to get the page to rebuild.

The montage.cgi file is a shell script that builds the image file. You can log in and look at this shell script on the Course Linux Server using this pathname: /var/www/html/montage.cgi
