1.2. Standards and Common Interfaces

Common standards bridge the gaps between the different types of UNIX. The user's decision of what variant of UNIX to use impacts its portability and, therefore, its potential market. If you are a program developer, clearly, the market for your program is limited to the people who use the same system you developed on unless you take the trouble to port it. Standards come about from the need for a specification of a common programming interface that would facilitate having code developed on one operating system run on another with minimal or no patching. Various standards organizations have set out to define specifications for UNIX. POSIX, formed by the Institute of Electronic Engineers (IEEE), is a standard for a portable operating system for computer environments with which Linux aims to be compliant.
