Interix is a software product designed to provide a Unix-like environment on Windows operating systems. Originally developed as a separate product, it was acquired by Microsoft and integrated into Windows as part of the Windows Services for UNIX (SFU) package, which included tools to help Unix-based applications run on Windows. Interix provides a POSIX-compliant environment, which means it offers a set of standardized APIs and utilities that mimic the behavior of Unix systems.
