    Product Details

    • Preface/Scope
    Scope

    This part of ISO/IEC 9945 defines a standard source-code-Ievel interface
    to command interpretation, or shell, services and common utility
    programs for application programs. These services and programs are
    complementary to those specified by ISOIIEC 9945-1: 1990 (IEEE Std
    1003.1-1990) {S}, hereinafter referred to as POSIX.1 {S}. When the
    User Portability Utilities Option is included, this part of ISO/IEC 9945
    has additional scope. The list of utilities and features is extended to
    provide a common interactive environment for system users and program
    developers. This part of ISOIIEC 9945 has been designed to be used by
    both application programmers and system implementors. When the User
    Portability Utilities Option is included, it is also to be used by
    system users and program developers. However, it is intended to be a
    reference document and not a tutorial on the use of the services, the
    utilities, or the interrelationships between the utilities. The emphasis
    of this part of ISO/IEC 9945 without the User Portability Utilities
    option is on the shell and utility functionality required by application
    programs (including shell scripts) and not on the direct interactive
    use of the shell command language or the utilities by humans. When the
    User Portability Utilities Option is included, the emphasis is extended
    to support terminal users in a consistent manner across all conforming
    systems.
