UNIX VS. LINUX

Start

What is UNIX?

  • Usage of plain text for data storage.
  • Hierarchical file system.
  • Handling devices and some specific kinds of inter-process communication (IPC) as files.
  • Employing a huge number of software tools.
  • Multiple small, simple and modular programs which can be threaded together via a command-line interpreter using pipes.

Unix is considered as the mother of most of the operating systems. The design of Unix systems includes:

UNIX Architecture

What is LINUX?

Linux is not Unix, but it is a Unix-like operating system. It is derived from Unix and it is a continuation of the basis of Unix design. It works in a way similar to Unix systems, however, it is not necessary that they conform to Single UNIX Specification (SUS) or similar POSIX (Portable Operating System Interface) standard.

Differences between UNIX and LINUX

LINUX

UNIX

  • Designed as a general-purpose scalable platform for a broad set of applications.
  • Broadly available as configurable software download and installer.
  • Free community support.
  • Interfaces often evolve
  • Frequent updates, with quick bug fixes
  • Typically designed for a narrow audience with a defined set of target platforms and applications.
  • Typically shipped along with hardware
  • Paid support available from a number of service providers.
  • Interfaces usually stable
  • Infrequent updates, and fixes may take time

Differences between UNIX and LINUX

LINUX

UNIX

  • Supports almost all file systems used across operating systems
  • Breadth of system administration tools often with limited focus
  • Preferred OS for cloud deployment and data centers primarily for economic reasons
  • Scalability achieved using clusters, grids or cloud.
  • Most of the command line and graphical utilities are similar to Unix
  • Most versions support two or three file systems.
  • Each version typically has a mature system administration tool
  • Preferred OS for special purpose server requirements
  • Scalability achieved using clusters or grids
  • Most of the command line and graphical utilities are similar to Linux
