Abstract

The Command Line Interface (CLI) is a very good tool, but it can scare people away because of the strict commands you have to type in. Command-line interfaces are also very error-sensitive when it comes to typing commands into your computer and if you accidentally run a command that is harmful then you might erase everything on your computer. In addition to this, the basic shells that have been created for many years starting with Bash, usually have little to no help for the user. This leads to the purpose of this review. This review will discuss the ideas behind building a lightweight custom shell, programmed in C using the SAGE (Suggestive Auto-Command Generate Environment) prototype to demonstrate how the performance of a custom shell was developed. The advantages of building a lightweight shell are that you can provide intelligent input correction, proactive safety checks (before actually executing a command), replayable command history, and the ability to monitor system resources before executing commands without overloading your CPU and/or RAM. This article gives a solid foundation for how the SAGE prototype will help evolve the standard command-line interface (CLI) into a more intelligent, sustainable, and productive assistant to the user.
