What is Tcsh?

Tcsh (pronounced tee see shell) is a variant of a classic UNIX shell, the C shell. Shell is a UNIX term for the interactive user interface within an operating system. The shell is the layer of programming that understands and executes the commands a user enters. In some systems, the shell is called a command interpreter. A shell usually implies an interface with a command syntax (think of the DOS operating system and its "C:\>" prompts and user commands such as "dir" and "edit"). The C shell was designed around a C-type language syntax so programmers would have an intuitive interface. Tcsh is an enhanced but completely compatible version of the Berkeley UNIX C shell.
