This is a repository for the projects assigned in Professor Eggert's Spring 2014 class. The README.txt contained in each project was for submission purposes.

We built a UNIX shell that analyzes the dependencies of commands in a shell script and runs top-level commands in parallel. We also implemented the design project for part A, which recognizes the redirection operators.

We wrote a Linux kernel module that implements a ramdisk that supports read/write operations and a special read/write locking mechanism to allow a process to gain exclusive access to the ramdisk.
