Information technology — Portable Operating System Interface (POSIX) — Part 2: Shell and Utilities
This part of ISO/IEC 9945 defines a standard source-code-level interface to command interpretation, or "shell," services and common utility programs for applica- tion programs. These services and programs are complementary to those specified by ISO/IEC 9945-1: 1990 (IEEE Std 1003.1-1990) {8}, hereinafter referred to as "POSIX.1 {8}." When the User Portability Utilities Option…

Information technology — 8 mm wide magnetic tape cartridge dual azimuth format for information inter...
This International Standard specifies the physical and magnetic characteristics of an 8 mm wide magnetic tape cartridge to enable interchangeability of such cartridges. It also specifies the quality of the recorded signals, the format and the recording method, thus allowing, together with ISO 1001 for Magnetic Tape Labelling, full data interchange by means of such magnetic tape cartridges. It is…

This International Standard specifies the physical and magnetic characteristics of a 12,7 mm wide, 48-track magnetic tape cartridge, to enable interchangeability of such cartridges. It also specifies the quality of the recorded signals, a format — called Digital Linear Tape 1 (DLT 1) — and a recording method. Together with a labelling standard, e.g. ISO 1001, it allows full data interchange by…
