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
For example, a custom embedded operating system might implement a command-line interpreter with syntax and commands
