• Read Unix Interface Design Patterns from TAOUP
• Follow the link in the last section to Chapter 8 and read the introduction to learn what is meant by “domain-specific minilanguage”

Self Study

1. Notice that for the most part the discussion about design patterns doesn’t mention specific programming languages. Why is that? How can this work toward your advantage when learning a new programming language or reading a program written in a language you are not familiar with?

2. While common in the Unix environment none of the design patterns discussed in this section are necessarily uniq to Unix or Unix-like systems. Do you recognize any of the patterns discussed in programms you have written for other classes or non-Unix environments?

3. One pattern that you are probably less likely to see in non-Unix environments are those listed under the ‘Separate Engine and Interface’ heaing. Why might these patterns be less likely to appear outside of the Unix community. Are the reasons technological, cultural or both?
