The TC Shell (tcsh) performs the same function as the Bourne Again Shell and other shells: It provides an interface between you and the Linux operating system. The TC Shell is an interactive command interpreter as well as a high-level programming language. Although you use only one shell at any given time, you should be able to switch back and forth comfortably between shells as the need arises (you may want to run different shells in different windows).
