INTRODUCTION

The C shell is an interactive command and programming language that provides an interface to UNIX. As an interactive command language, it is responsible for reading and executing the commands that you enter at your terminal. As a programming language, its special commands allow you to write sophisticated programs. It also provides the ability to customize your working environment.

The C shell was developed as a replacement for the standard Bourne shell, and is found on most systems running UNIX-based systems. It provides a number of features not found in the standard Bourne shell, such as:

Command  aliases

Enhanced  directory navigation features

Filename  completion

History  substitution

Job  control

There are also shareware versions of C Shell-like variants, most notable Tcsh. An Internet search should get a good number of hits on this version of the C Shell.
