  • Shell
    • The command shell is the nucleus of the Midas system.
    • It is the piece of software that receives and reacts to text commands from the user or interoperating software.
    • Throughout the history of the Midas family, there have been numerous shells with various features, some welcomed and others despised.
    • For flexibility, NeXtMidas and X-Midas provide two basic shell operating modes:
      Interactive
      The Midas shell is explicitly entered. Further interaction is done within the shell.
      One-Shot
      Midas starts up, runs a single command, and then exits.
      It is not uncommon for the "single" command to be a full-scale application.
