Reminder: There are now two quizzes that you need to complete (five times each) on Brightspace 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.

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:
Make notes from the worksheets on how each command works. What do the options used in the worksheets mean, for each command? (See the weekly List of Commands.)
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 get a copy here: Course Introduction: Install Libre Office.
Worksheet #06 is for the optional VIM Bonus Assignment (extra credit):
vim
vimtutor
program on the CLS.Worksheet #08 is for Assignment #09 HTML.
chmod, ls -lid, umask
Worksheets prepare you for the upcoming assignments.
This course has two midterm tests (10%, 15%) and one final exam (40%).
Note that your upcoming Midterm Test #2 is worth more than five assignments put together. Don’t spend all your time doing an assignment at the expense of studying the Practice Tests and Answers for the Midterm Test.
Follow this link to see all your upcoming Quizzes and Tests. The dates are also posted on the Course Home Page and on Brightspace CST8207.
For full marks, read the Test Instructions (all the words) before your midterm tests.
Midterm tests take place in your one-hour lecture class, not in your lab period.
Take notes in class! Keep a pad open on your desk.
In class I showed you how to decode the Mystery Puzzle File that is part of upcoming Assignment #11 HTML.
Try the pstree
and top
commands.
Don’t forget to finish your five Brightspace quiz attempts for each of the Midterm 1 and Midterm 2 quizzes. There is a third quiz available to prepare for the Final Exam. Do at least five attempts in all three quizzes.
Regarding Assignment #09, Assignment #11, and Assignment #12:
Keep a notebook with a List of Commands in it.
- You need to write down yourself what each command does.
- Check the updated list of commands each week.
- I will check for this list in your lab periods.
- Bring your notes to class! Stop wasting time looking up commands.
Are you making notes from the worksheets on how each command works?
Know (for the assignment) the three commands that are directory operations that manipulate file names; they don’t touch the file data and don’t need any permissions on the file data.
The diff
command compares two files: diff file1 file2
vimdiff
and (for a GUI only:) gvimdiff
meld
Don’t create files or directories that anyone (“other”) can write, except
the few required ones in the one Assignment #09 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 to look for them:
world-writable
in all the course notes.This is part of Assignment #09 HTML. You can do it now, if you Read All The Words.
chmod 755
on your public_html
directory.http://cst8207.idallen.ca/~
abcd0001
where abcd0001
is replaced with your CLS userid.

Many students find that hiring a personal tutor helps them get through the first term. Financial assistance is available. See the Tutoring heading in the Course Introduction.
You are not paranoid if they really are out to get you! See the Week 03 Notes HTML for command pipelines to count the ongoing attacks on the CLS.
