Why UNIX?

Control

  • Commands often provide complete access to the system and its devices.
  • Most devices can be manipulated just like files

Flexibility

  • Commands are just programs.
  • Commands have common interface to allow inter-operation with other commands.
  • Unix offers thousands of tools that can be combined and recombined.

Reliability

  • Commands are typically lightweight since they typically do little more than invoke operating system calls.
  • Unix is hard to crash.
  • Provide multitasking, each user can perform multiple task easily.

Powerful

  • Unix as an operating system can support almost any kind of software.
Note :
         UNIX was developed at AT&T Bell Laboratories by Ken Thompson and Dennis Ritchie. It was finally written in C.
         All UNIX flavors today offer a graphical user interface (GUI) in the X Window system. But the strength of UNIX lies in its commands and options.
