A shell is a command line interpreter that accepts and runs commands. It is a command language interpreter that execute commands read from input devices such as keyboards or from files. In den nächsten Abschnitten stelle ich QBasic, einen BASIC-Interpreter für DOS (läuft auch unter Windows und emuliert auch unter Linux) und FreeBASIC, BASIC-Compiler für Windows und Linux, vor. Bas is an interpreter for the classic dialect of the programming language BASIC. BASIC for Linux(R), Mac(R) OS X and Windows(R) It is a new programming language, a further BASIC dialect and is related to VB.NET(R), Visual Basic(R), Visual Basic for Application(R) and Java(R). Bash aka the Bourne Again Shell is the default command-line interpreter in most Linux distros nowadays. Learning bash shell scripting will allow you to understand other shell scripts much faster. The Bywater BASIC Interpreter (bwBASIC) implements a large superset of the ANSI Standard for Minimal BASIC (X3.60-1978) and a significant subset of the ANSI Standard for Full BASIC (X3.113-1987) in C.
