  Furthermore, typing is far faster than clicking on graphical user interfaces.
• Some systems are unable to provide graphical user interfaces due to a lack of resources.
  Command line interpreters can be used in these situations.
• In scientific environments, command line interpreters were frequently utilized by scientists and engineers.
  Command line interpreters are also preferred by technically advanced users over graphical user interfaces
