POSIX (Portable Operating System Interface) is a set of standard operating system interfaces based on theUnixoperating system. The most recent POSIX specifications -- IEEE Std 1003.1-2017 -- defines a standard interface and environment that can be used by an operating system (OS) to provide acce...
The POSIX standard that will affect most end-users is POSIX.2, which governs the behavior of the shell and various standard utility programs. On a POSIX-compliant system, all of the options should be the same, no matter which operating system variant you're using. The other POSIX standards ...
