2.1.1 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 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 online viewing: Worksheet #02 HTML – Using standard Linux commands I
- PS1, cd, find, less, ls, man, mkdir, passwd, pwd, rmdir
Worksheet #03 ODT online viewing: Worksheet #03 HTML – Using standard Linux commands II
- cat, clear, cp, find, grep, history, less, man, mv, rm, sleep, touch
Worksheet #04 ODT online viewing: Worksheet #04 HTML – GLOB Patterns and Aliases

5 Monospace Fixed-Width (Courier) Fonts on Tests

When you are asked to count arguments that are separated by spaces, the command lines are always printed using a monospace, fixed-width, Courier-style font where every character, including a space, has the same width. If you couldn’t fit a capital M into the gap, there is no space there:

MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
 'def' ' ghi ' it's 'mno '  ' pqr'   's' '' ' '
MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
