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? - Read All The Words, Do, and then Submit via Blackboard: - Bonus (optional) [Assignment #04 HTML] -- the VIM text editor - [Assignment #05 HTML] -- GLOB wildcard patterns, finding files using GLOB, redirection and pipes - Bonus (optional) [Assignment #06 HTML] about Midterm #1 - [Assignment #07 HTML] -- start-up files, environment, search PATH, quoting, hard and soft links, disk usage - Really do **Read All The Words**. You don't get a second chance to get it right. ### 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. 2. Worksheet. 3. Assignment. 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]. - [Worksheet #04 ODT] -- shell GLOB patterns and Aliases - [Worksheet #04 PDF] - [Worksheet #04 HTML] - shell GLOB patterns (wildcards), Aliases: `alias, sum, unalias` - [Worksheet #05 ODT] -- shell I/O redirection (including pipes) - [Worksheet #05 PDF] - [Worksheet #05 HTML] - shell I/O redirection, `date, head, nl, tail, tr, wc` - [Worksheet #06 HTML] -- *Optional* Bonus VIM Text Editor Practice - This is an *optional* worksheet for a BONUS assignment using `vim` - Optional command-line VIM tutorial: the `vimtutor` program on the CLS. - Bonus (optional) [Assignment #04 HTML] -- the VIM text editor - Read [The VI (VIM) Text Editor] Worksheets prepare you for the upcoming assignments.

Put these dates into your phone! Use the **Name Game** link to test your name before the test. I don't answer questions about the instructions during the test. 1. **First Midterm test:** 45 minutes; in lecture class on Wednesday in Week 6 (Oct 12) 2. **Second Midterm test:** 45 minutes; in lecture class on Wednesday in Week 10 (Nov 9) Tests take place in class in your 50-minute lecture period, not in your lab period. Each midterm test is 45 minutes long and contains approximately 45 multiple-choice questions similar to those found in [Practice Tests and Answers]. ### Midterm Test #1 -- Wednesday October 12 - Midterm #1 takes place on Wednesday, October 12 (Week 6) in your scheduled lecture hour (not in your lab period). - For full marks, you must read the [Test Instructions] before the test for important directions on how to enter your name, answers, your lab (not lecture) section number, and the test version number on the question sheet and the mark-sense forms. - There may be more questions on the test than you can answer in the time allowed; answer the ones you know, first. - A set of practice questions and answers for the first midterm test is posted: [Practice Tests and Answers]. - The tests use the semicolon `;` to separate multiple commands on the same line, to save space and paper, e.g. three separate commands can be written on one line like this: `date ; echo "hi" ; ls` - **Do not use semicolons as an interactive human user!** Type each command on its own line with the \[Enter\] key. - Blackboard has some quizzes taken randomly from the practice test. The full practice test itself is *not* part of your course grade, but the quizzes *are* part of your course grade. See below. See the [Week 04 Notes HTML] for how to earn all your quiz marks. - See the [Course Outline] for the mark weight of all the quizzes. Notes from the Classroom ======================== - **Take notes in class!** Keep a pad open on your desk. - Monday is a holiday this week (Thanksgiving) -- there are no classes on Monday. Students with lab periods on Monday may attend any of the other six lab periods this week. The Thursday 10am section 020 theory/lecture class in C346 is cancelled this week. - Note that your Midterm Test #1 on Wednesday October 12 is worth more than three 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. - I am holding two Review Classes to answer your questions about the first Midterm Test: - Review #1: Friday October 7 13:00 -- 14:00 in J208 - Questions done: 22 38 40 48 58 64 80 89 96 98 100 103 121 144 - Review #2: Tuesday October 11 16:00 -- 17:00 in T304 - Questions done: 7 15 17 19 52 57 74 75 76 78 89 91 92 94 102 104 117 127 137 187 210 You must bring your questions from the practice test or from any of the many previous term midterm tests. I will show you how to best answer any of those questions. - ASCII-Art Weather. Widen your terminal to 125 characters or more and type this at any shell prompt: `curl wttr.in/ottawa` - See also - A [Command Line Primer for Beginners] Commands Used ------------- Keep a notebook with a [List of Commands][List of Commands You Should Know] in it. - You need to write down yourself what each command *does*. - I will check for this list in your lab periods. - Check the updated list of commands each week. - 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! - Useful command: `hostname` - Needed for [Assignment #07 HTML] - Three useful options to the `wc` command (often used in tests): - `wc -l` - `wc -w` (Needed for your second midterm test.) - `wc -c` - Know (for the assignment) the three commands that are [directory operations][Hard links and Unix/Linux file system index nodes (inodes)] that manipulate file names; they don't touch the file data and don't need any permissions on the file data. Tutoring ======== Many students find that hiring a personal tutor helps them get through the first term. Financial assistance is available. See [Algonquin Peer Tutoring] Moving Assignment 2 files ========================= If you want to clean up files in your HOME directory, you can create an `assignment02` directory under `Assignments` and move all your Assignment 2 files into it. The checking program will check there for your files. ![Take Notes in Class] -- | Ian! D.
