Unixhenkisiä

Unixhenkisiä is a Finnish term that can be translated to "Unix-like" or "Unix-family." It refers to a broad category of operating systems that are either directly derived from or heavily influenced by the original AT&T Unix. These systems share a common design philosophy and set of characteristics, even if they are not direct descendants of the original Unix source code.

Key features often found in Unixhenkisiä operating systems include a hierarchical file system, command-line interface (CLI) as a primary means of interaction, multitasking capabilities, multi-user support, and a rich set of utilities and tools. The concept of "everything is a file" is also a prevalent characteristic, meaning that devices, processes, and other system resources are represented as files within the file system.

Examples of Unixhenkisiä operating systems are numerous and diverse. This category includes the various distributions of Linux, such as Ubuntu, Fedora, and Debian, which are arguably the most widely used Unix-like systems today. It also encompasses macOS and its predecessors, which are based on Darwin, a Unix-certified operating system. Other notable examples include BSD variants like FreeBSD and OpenBSD, as well as Solaris and AIX, though these are less common in general consumer use. The shared heritage and design principles allow for a high degree of interoperability and portability of software and knowledge across these different systems.
