Product Standard

NAME

Commands and Utilities V4

LABEL FOR LOGO

No label.

DESCRIPTION

This Product Standard provides a command interface to a range of system utilities. It includes conformance to the Shell and Utilities volume of IEEE Std 1003.1-2001 and ISO/IEC 9945-3:2002.¹

It is an enhanced version of the Commands and Utilities V3 Product Standard.

The principal enhancements are:

• The c99 utility has been added to support ISO/IEC 9899:1999 (C Language)² included in the Internationalized System Calls and Libraries Extended V3 Product Standard. This utility replaces the c89 utility which has been withdrawn.

• The iconv utility is added from the P1003.2b³ draft standard.

• Many utilities have additional behavior for handling of symbolic links. This feature is incorporated from the P1003.2b draft standard.

• A set of Batch utilities has been incorporated from IEEE Std 1003.2d-1994.⁴

• Deficiencies have been corrected as a result of incorporation of IEEE PASC Interpretations and The Open Group Corrigenda and Resolutions.

CONFORMANCE REQUIREMENTS

Human-Computer Interface

Shell and Utilities, Issue 6⁵ and Base Definitions, Issue 6,⁶ Section 6.1, Portable Character Set, Table 6-1, Portable Character Set.

Portability Interface

Shell and Utilities, Issue 6 and Base Definitions, Issue 6.

Programming Language Environment

Command Language as defined in Shell and Utilities, Issue 6 and Base Definitions, Issue 6.

Interoperability

• Data Interchange Formats

  Shell and Utilities, Issue 6, 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 Extended V3.

OVERRIDING STANDARDS

The Base Specifications, Issue 6 are technically identical to IEEE Std 1003.1-2001 and ISO/IEC 9945:2002 (they are the same documents) and are maintained by the Austin Group, a joint working group of the IEEE, The Open Group, and ISO/IEC SC22 WG15. Deference is thus not applicable.⁷

INDICATORS OF COMPLIANCE

A Test Report from a currently authorized release of the VSC5 Test Suite.

MIGRATION

Obsolescent features from Commands and Utilities, Issue 5⁸ are not carried forward in this Product Standard. The c99 utility replaces the c89 utility, which has been withdrawn. Otherwise, there are no major incompatibility issues in migrating from a system registered as conformant to the Commands and Utilities V3 Product Standard.

Detailed migration information can be found in The Authorized Guide to Version 3 of the Single UNIX Specification.⁹
