The next generation of command line interfaces

The move to WIMPS interfaces has delivered excellent models and interfaces for simple operations on personal computers. Unfortunately, this has not been matched by the development of models and interfaces for the operations required in more complex systems, traditionally provided by applications such as the "csh," and more recently AppleScript. We introduce and demonstrate the use of the Prograph system, together with a sample of suitable utilities, as the appropriate tool for shell-type operations in a WIMPS environment.
