SUS may refer to any of the following:

  1. The Single Unix Specification, also known as SUS, is a group of operating system standards that define what kind of operating system can officially be given the “Unix” name. The standards started being developed in the 1980s when organizations needed a way to ensure their software could be re-used on multiple Unix platforms. Today, the SUS guarantees that certain commands do the same thing on different systems and is crucial to developers and end users alike.

SUS compliant operating systems

The SUS is currently defined and maintained by the Austin Group, a subset of the Open Group. Operating systems that are compliant with the Single Unix Specification include:

  • OS X
  • Oracle Solaris
  • Fujitsu Solaris
  • HP-UX
  • AIX
  • z/OS
  • K-UX
  • IRIX
  • SCO UnixWare and OpenServer
  1. When used in chat and gaming, SUS is short for “suspicious.” The term became popular in the gaming community surrounding Among Us. SUS is used when someone finds someone or something fake, suspicious, dishonest, or untrustworthy. For example, when you get a phishing e-mail asking for you to log in to your bank account to verify your balance, it’s SUS.
