What is Unix-based systems?

Unix-based systems are a family of operating systems that trace their origins back to the original Unix developed at Bell Labs in the late 1960s. They are characterized by a hierarchical file system, the concept of treating devices as files, the use of command-line interface (CLI) tools, and the ability to pipe the output of one command into the input of another. Unix-based systems are known for their stability, security, and portability. They are commonly used in servers, workstations, and mobile devices. Examples include macOS, Linux, Solaris, and FreeBSD. They are often used for software development, system administration, and enterprise-level applications.
