Commands and Utilities V2

Category: Operating System Services [CV]

This Product Standard provides a command interface to a range of system utilities. It includes strict conformance to ISO/IEC 9945-2:1993 (POSIX-2). It differs from the Commands and Utilities Product Standard in that strict conformance to the relevant CAE Specifications is mandatory. Conformance to this Product Standard does not require the extensions to the cc and c89 commands identified by the UNIX EXTENSION feature group to be supported. Note that support of this extended functionality is required by certain Product Standards.

Product Standards are explained in Practical Guide to the Open Brand
