POSIXinspired

POSIXinspired is a conceptual term used to describe software, systems, or design philosophies that draw upon or emulate the principles of the POSIX standard without necessarily being fully compliant with it. The Portable Operating System Interface (POSIX) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. Systems that are POSIX-compliant aim for a high degree of interoperability, particularly in their command-line interfaces and system call behaviors.

Software or systems described as POSIXinspired might adopt core POSIX concepts such as a hierarchical file system, a common set of utilities (like `ls`, `cp`, `mv`), shell scripting capabilities, and a standardized API for process management and inter-process communication. However, they may not adhere to every single detail of the POSIX specifications. This could be due to various reasons, such as targeting different hardware architectures, focusing on specific performance optimizations, or incorporating unique features not covered by POSIX.

For example, a custom embedded operating system might implement a command-line interpreter with syntax and commands similar to a POSIX shell, but it might not expose the full POSIX API for all system services. Similarly, an application might use POSIX-like file handling or process creation techniques without being a full POSIX-certified operating system. The term emphasizes the influence and adoption of POSIX's foundational ideas in creating interoperable and familiar computing environments, even when strict adherence is not the primary goal.
