USG Unixoperating system /U-S-G yoo'niks/ Refers to AT&T Unix commercial versions after Version 7, especially System III and System V releases 1, 2, and 3. So called because during most of the lifespan of those versions AT&T's support crew was called the "Unix Support Group". Compare BSD. [Jargon File]
