You don't get a second chance to get it right. ### Worksheets 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 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 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` Lab work this week ------------------ - Your instructor will show you how to log in to the [Course Linux Server] and use some simple commands.
