What is a Command Driven Interface?

• A Command Line Interface allows a user to
  interact with a computer system by typing in
  commands.
• Any command which is entered must be typed in the
  correct syntax to perform the operation.

Examples of a Command Driven Interfaces are Dos,
Linux and Unix.

Advantages

• Faster than using Menus and Icons on a GUI
  interface.
• Less memory required, because of no graphics on
  the interface.
• Works on computers with limited hardware and
  software.
• Experienced users can use this system faster than
  others.
• Complex commands can be entered to customise the
  operating system for a particular user.
• Does not require a Windows Operating system to
  work.

Disadvantages

• People with limited knowledge of DOS may find the
  interface confusing and hard to use.
• Errors in commands can cause the operation to
  fail and can be very time consuming.
• Any errors in typing will require the user to
  re-type command. This time consuming and
  frustrating.
• Commands have to be learnt, especially in UNIX
  where there are hundreds.
• The interface is not attractive compared to a GUI
  interface.

Unix
UNIX is a general-purpose software, which
incorporates multi-users written in C. UNIX
unlike others is available to a wider variety of
platforms, like computers from different
manufacturers.

Linux
Created by Linus Torvalds, who was Finnish.
Developed by thousands of volunteers. Its free
and can be downloaded of the net. The only
biggest problem of LINUX is that it will not run
most software commonly on a windows pc.
