As a programming language, the Bourne shell has been discussed partly in Chapter 9. In order to program more advanced scripts, it is necessary to learn more statements and commands that can be used to program. In this chapter, the discussion on program control flow statements will be continued, which includes case, while, until, break, and continue statements. Except these statements, there are some more topics: how to process numeric data, the Bourne shell support of functions, and how to debug shell scripts.
