 | | In this chapter, we examined how to execute programs, which can be viewed as the primary purpose of the UNIX operating system. The most common tasks performed on a UNIX system require the ability to execute programs, although much of this is hidden from the user by the shell. Many of these same tasks require the ability to execute multiple programs and tie them together with pipelines or interprocess communications facilities; this is discussed in detail in Chapter 13, Interprocess Communication. | |
