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]. Worksheets #04 and #05 require you to have read [Shell GLOB patterns] and [Shell I/O Redirection]: - [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 is for the optional VIM Bonus Assignment (extra credit): - [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. Upcoming tests and exams ------------------------ 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. 1. First Midterm test: 45 minutes; in your one-hour lecture class in Week 6. 2. Second Midterm test: 45 minutes; in your one-hour lecture class in Week 10. 3. Final Exam -- the date is now posted on ACSIS. Tests take place in your one-hour lecture class, not in your lab period. You must write the test in the lecture class in which you are registered. ### Practice Test #1 and Brightspace Quiz #2 [Practice Tests and Answers] -- practice questions for Midterm Test #1. [Quizzes and Tests] -- Quiz #2 is taken from Practice Test #1 and is good practice for your upcoming Midterm Test #1 in Week 6. Notes from the Classroom ======================== - **Take notes in class!** Keep a pad open on your desk. - Due to the Monday holiday and Midterm tests, you have no new lecture material this week. Attend any lab period for help with the questions on the [Practice Tests and Answers]. - Note that your upcoming Midterm Test #1 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. - You will need to learn a text editor. I recommend [The VI (VIM) Text Editor]. Commands Used ------------- > 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! Marking Scheme for Assignment #06 ================================= Bonus (optional) [Assignment #06 HTML] may be done after you get your marks email and question sheet back for Midterm #1. You can use this bonus work to optionally improve your mark on the first midterm test. See the assignment for details. Your question sheet will be brought to the lab section you wrote on the question sheet, if it is a valid lab section. See the Brightspace course Announcements for details (under "bonus Assignment 6 details"). Searching the course notes ========================== I received an email like the text below from a student who was working on a problem for over two hours: > I have spent almost 2 hours on Task 4.6 and I still can't find the 100 > files. \[...\] I think the problem is searching for warez case-insensitive. > I know we learned this before, but I just can't find it in my notes. This is not good use of student time for two reasons: 1. Don't spend more than 15 minutes on a problem! Your time as a student is valuable. See the [Course Introduction: fifteen minute rule] 2. I showed you how to search the course notes for keywords in [Assignment #05 HTML]: - In section [3.2 Searching the course notes on the CLS] - In section [4.5 Searching for text inside files (e.g. course notes)] You have a search tool that will find keywords inside the course notes. Please use it and save yourself time. Who is using the VIM editor? ============================ This page may take a minute or two to load; be patient: [Who is using the VIM editor?] Tutoring ======== 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]. SSH and HTTP Attacks on the CLS =============================== 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. Locked out of the CLS ===================== When you are locked out, [follow the directions] in the notes to get your IP address re-enabled. ![Take Notes in Class] -- | Ian! D.
