You can't do the assignments without having done the worksheets first. 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 #02 ODT] -- Using standard Linux commands I - [Worksheet #02 PDF] - [Worksheet #02 HTML] - `PS1, cd, find, less, ls, man, mkdir, passwd, pwd, rmdir` - [Worksheet #03 ODT] -- Using standard Linux commands II - [Worksheet #03 PDF] - [Worksheet #03 HTML] - `cat, clear, cp, find, grep, history, less, man, mv, rm, sleep, touch` - [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] Lab work this week ------------------ - Work on the ODT or PDF [Worksheet #04 HTML] and [Worksheet #05 HTML] so you can do [Assignment #05 HTML] -- GLOB wildcard patterns, finding files using GLOB, redirection and pipes - The worksheets will be easier once you read [Finding Files], [Shell GLOB patterns] (wildcard pathname matching) and [Shell I/O Redirection] (including Pipes). - Read [The VI (VIM) Text Editor] and optionally do the bonus [Assignment #04 HTML]. - Do Bonus (optional) [Assignment #06 HTML] about Midterm #1 - There will be 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.

First Midterm test: 45 minutes; in lecture class noon Friday in Week 5 (Feb 12) 2. Second Midterm test: 45 minutes; in lecture class noon Friday in Week 9 (Mar 18) 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 -- February 12 - Midterm #1 takes place on Friday, February 12 (Week 5) 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. This second quiz set is one of several marked quizzes in this course. The quizzes are part of your course grade. 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. From the Class Notes link on the Course Home Page ================================================= - [Course Home Page] - [All Weeks] - Review last week. Did you do everything assigned last week? From the Classroom Whiteboard/Chalkboard ======================================== - **Take notes in class!** Your in-class notes would go here. - 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! - Bring your notes to class! Stop wasting time looking up commands. Fifteen minute rule ------------------- Your time as a student is valuable. See the [Week 03 Notes HTML]. Commands -------- 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. Locked out ---------- The CLS will lock out your IP address if you can't type your own userid correctly. If this happens, you have to follow the posted directions to have me unlock your IP address. You can change to another IP address. You can always come to school where no IP addresses are locked out. ![Take Notes in Class] -- | Ian! D.
