Topic: POSIX


Technically, POSIX is the name for a set of related standards that specify the user and software interfaces for Unix operating systems.

In the past, there were many systems call Unix. They seemed similar, but had differences. Differences that made writing programs or simply using them difficult. POSIX was created to make all these different flavors of Unix the same. Although Unix systems that choose to follow POSIX may (and usually do) still have stuff beyond what POSIX defines.
