Linux Shell

By: Thomas Bowlin
For EKU CSC400, Fall 2017
Dr. Zhang

System Overview

For Operating Systems class, we were tasked with creating a simple command line shell that works in Linux Ubuntu. The system was developed in a VirtualBox Ubuntu 17.10 installation, completely in the C programming language.

Technologies: Ubuntu, Vim, C

System Requirements

The shell had to support the following commands:

  • cd
  • clr
  • dir
  • echo
  • quit

Additionally, the shell had to interpret all other commands as program invocation, which is done by forking and executing the new program as a child process.
