• We continue in the notes with `elif`, `case`, etc.

## 2.2 Assignments, Quizzes, and Lab work this weekIndex

Reminder: There are now three quizzes that you need to complete on Brightspace as part of your term Quiz mark. The Quizzes are not optional; see Quizzes and Tests.

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
• The checking program has a feature to check just one of your scripts.
• OPTIONAL: Do Bonus Assignment #10 HTML to improve your Midterm #2 score.
• This affects only your Midterm #2 score, not your Assignment score.
• 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!

### 2.2.1 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:

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.

Worksheets prepare you for the upcoming assignments.

## 2.3 Upcoming tests and examsIndex

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

For full marks, read the Test Instructions (all the words) before your midterm tests.

1. First Midterm test: Done.
2. Second Midterm test: Done.
3. Final Exam: The date is now posted on ACSIS: Thursday December 13, 8am to 11am in the Gymnasium. Details are in Quizzes and Tests.

# 3 Notes from the ClassroomIndex

• Take notes in class! Keep a pad open on your desk.

• Look at the Practice Tests and Answers related to the Final Exam. You can bring your questions to your lab periods and your instructor will go over them with you.

• Check your EMail, especially when creating CRON jobs. One student had generated over 2,600 email messages (one per minute) using a CRON job that failed. (I deleted the job.)

• Don’t forget to finish your five Brightspace quiz attempts for each of the Midterm 1 and Midterm 2 quizzes. There is now a third quiz available to prepare for the Final Exam. Do five attempts in all three quizzes.

• Nobody should have any files larger than 1MB in their CLS account. If you have uploaded an image that is larger than 1MB, you should make it smaller using the `convert` command directions given in the Student Web Site page from Assignment #09.

• “The Bash Academy is an initiative to promote the bash shell language and educate people on its use.” http://www.bash.academy/

• Regarding world-writable files in your account: See last week’s notes.

## 3.1 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.

# 5 Who is using the VIM editor?Index

This page may take a minute or two to load; be patient: Who is using the VIM editor?

# 6 TutoringIndex

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.

# 7 SSH Attacks on the CLSIndex

You are not paranoid if they really are out to get you! See the Week 03 Notes HTML for command pipelines to count the SSH attacks on the CLS.

# 8 Locked out of the CLSIndex

When you are locked out, follow the directions in the notes to get your IP address re-enabled.
