Product Standard

NAME

Commands and Utilities V2

LABEL FOR LOGO

No label.

DESCRIPTION

This Product Standard provides a command interface to a range of system utilities. It includes conformance to ISO/IEC 9945-2:1993 (POSIX-2).¹

It differs from Commands and Utilities in that strict conformance to the CAE Specifications identified below is mandatory.

Conformance to this Product Standard does not require the extensions to the cc and c89 commands identified by the X/Open_UNIX_EXTENSION Feature Group to be supported.

Note that support of this extended functionality is required by certain other Product Standards.

CONFORMANCE REQUIREMENTS

Human-Computer Interface

Commands and Utilities, Issue 4, Version 2² and System Interface Definitions, Issue 4, Version 2.³

These specifications are technically identical to Commands and Utilities, Issue 4⁴ and System Interface Definitions, Issue 4⁵, which they supersede, except for the X/Open_UNIX_EXTENSION additions to the cc and c89 commands, which are not required for conformance to this Product Standard.

Portability Interface

Commands and Utilities, Issue 4, Version 2 and System Interface Definitions, Issue 4, Version 2.

The extensions identified by the X/Open_UNIX_EXTENSION in the cc and c89 commands of Commands and Utilities, Issue 4, Version 2 are not required.

Programming Language Environment

Command Language as defined in the Commands and Utilities, Issue 4, Version 2 and System Interface Definitions, Issue 4, Version 2.

Interoperability

• Data Interchange Formats

  Commands and Utilities, Issue 4, Version 2, cpio and extended tar archive file formats, pax utility.

• Communications Interfaces and Protocols

  None.

OPERATIONAL ENVIRONMENT

Not applicable.

PORTABILITY ENVIRONMENT

Internationalized System Calls and Libraries, Internationalized System Calls and Libraries Extended, or Internationalized System Calls and Libraries Extended V2.

OVERRIDING STANDARDS

ISO/IEC 9945-2:1993 (POSIX-2).

INDICATORS OF COMPLIANCE

A Test Report from a currently authorized release of the VSC4 Test Suite.

MIGRATION

Migration issues from XPG3 are defined in the XPG3-XPG4 Base Migration Guide.⁶

Migration issues from a product registered as conformant to the Commands and Utilities Product Standard are system-dependent, but determined by reference to its Conformance Statement.
