It contains code to execute a command or uses a command to read an external file having a code. The Unix Shell and windows command prompt are some examples of command interpreter.
Command Interpreters Vs Graphical User Interface
Command Interpreters work on text-based interfaces where the users can type their requests and queries as required and obtain the desired results.
In comparison to this, the Graphical User Interface (GUI) contains all the information in a visual form where icons, windows etc. can be used to access and manipulate data.
Experienced users find command interpreters much more useful as it is faster to type commands and get results. Normal users prefer graphical user interfaces as they are in a graphic format and easy to use.
