1.2 Assignments and lab work this weekIndex

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.

• Review last week. Did you do everything assigned last week?
• Assignment #09 HTML – setting permissions, mode, umask, personal web site
• Assignment #11 HTML – tar, processes, syslog, crontab, at, mail, shell script
• OPTIONAL: Do Bonus Assignment #10 HTML about Midterm #2
  • There is a checking program available to check your file format for this bonus assignment, but only people who Read All These Words will know about it. Wrong file format means no marks. Do not redirect or save the output of this checking program!

1.3 WorksheetsIndex

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).

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 #08 is for Assignment #09 HTML.

• Worksheet #08 ODT – Linux file system permissions (modes)
  • This Worksheet is a prerequisite for Assignment #09 HTML
  • Worksheet #08 PDF – PDF version
  • Worksheet #08 HTML – HTML version
  • chmod, ls -lid, umask

Worksheets prepare you for the upcoming assignments.

1.4 Upcoming tests and examsIndex

This course has two midterm tests (10%, 15%) and one final exam (40%).

• Put these dates below into your phone!
• Read the Test Instructions (all the words) before your tests and exam.
• Use the Algonquin Registered Name Game link in the Test Instructions to confirm the spelling of your name before the test.
• I don’t answer questions about the instructions during the test. Ask me in a lab period before the test.
• You must write the test in the lecture class in which you are registered.

2.1 Commands UsedIndex

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?
  • What do the options used in the worksheets mean, for each command?
  • Don’t copy and use options that you don’t understand!
