The second chapter is dedicated to MTS and UNIX. A brief history of both systems is given here. The third chapter is a tutorial on the the Shell in general, and a description of the Bourne Shell, and the C Shell follows. The last chapter is dedicated to the advantages and disadvantages of the Shell, and then the appendices follow.
