scope:

This document defines a standard for test methods for the interface to command interpretation, or shell, services and common utility programs for application programs. These test methods are derived from the definitions contained in ISO/IEC 9945-2:1993 (IEEE Std 1003.2-1992) {9}, hereinafter referred to as POSIX.2 {9}. The services and programs described in POSIX.2 {9} are complementary to those specified by ISO/IEC 9945-1:1990 (IEEE Std 1003.1-1990) {8}, hereinafter referred to as POSIX.1 {8}. This standard has been designed to be used by both verification suite authors and system implementors. However, it is intended to be a reference document and not a tutorial on the construction of verification suites or implementations.
