  Command line interpreter - Wikipedia, the free encyclopedia
A command line interpreter is a computer program which reads lines of text that the user types and interprets them in the context of a given operating system or programming language.
This requires the user to know the names of the commands and their parameters, and the syntax of the language that is interpreted.
Some command line interpreters also incorporate the interpreter engines of other languages, such as REXX, in addition to their own, allowing the executing of scripts, in those languages, directly within the command line interpreter itself.

 Command line interface - Wikipedia, the free encyclopedia
The term is usually used in contrast to a graphical user interface (GUI) in which commands are typically issued by moving a pointer (via a pointing device) to a zone of the screen and pressing a button mounted on the pointing device (clicking).
Command line interfaces require recall memory for routine functions that are repeated many times a day, instead of recognition memory, which some claim is the more natural way for humans to navigate and interact with their environment.
Command line interfaces are not efficient for multitasking; they do not offer the same ability to view multiple program outputs or content simultaneously.

 Command line interface - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-11-07)
A command line interface or CLI is a method of interacting with a computer by giving it lines of textual commands (that is, a sequence of characters) either from keyboard input or from a script.
The term is usually used in contrast to a graphical user interface (GUI) in which commands are typically issued by moving a pointer (via a pointing device) and/or pressing a key (that is, by "clicking", often on a key mounted on a mouse).
This advantage is magnified by tab completion and by the fact that programs intended to be run from the command line are often given very short names.

 Command line interpreter
A command line interpreter is a program which reads a line of text the user has typed and interprets this text in the context of a given system.
Command line interpreters have the advantage that the user may issue a lot of commands in a very terse and efficient way.
However for certain complex tasks GUIs are more difficult to use than a command line interface, because of the large number of menus and dialog boxes presented, and therefore a well designed command line interface is easier to use.

Commands are input with the help of a keyboard or similar device and are interpreted and executed by the program.
Command line interfaces usually provide greater flexibility than graphical user interfaces, at the cost of being harder for the novice to use.
Some commands require each option to be a separate argument, introduced by a new "-" or "/", others allow multiple option letters to be concatenated into a single argument with a single "-" or "/", e.g.

 COMMAND LINE INTERPRETER FACTS AND INFORMATION   (Site not responding. Last check: 2007-11-07)
A command line interpreter is a computer_program which reads lines of text that the user types and interprets them in the context of a given operating_system or programming_language.
In the 1970s, researchers began to develop graphical_user_interfaces (GUIs)to provide an alternative user interface for computers, whereby commands were represented by pictorial operations, rather than as textual descriptions.
(They are, after all, interpreters of an interpreted programming_language, albeit that in many cases the language is unique to the particular command line interpreter.) They will interpret scripts (variously termed shell_scripts or ''batch files'') written in the language that they interpret.

Then CINT as the command line interpreter, the CINT commands, and CINT's extensions to C++ are discussed.
An interpreter, optimized for code that changes often and runs a few times, is the perfect tool for this.
Variables created on the command line and in un-named scripts are in the interpreter's global scope, which makes the variables created in un-named scripts available on the command line event after the script is done executing.

 EVMS Command Line Interpreter   (Site not responding. Last check: 2007-11-07)
Because the EVMS CLI is an interpreter, it operates differently than command line utilities for the operating system.
This is important for command files because the EVMS CLI sees a command file as a single long command line.
These features allow a command in a command file to span several lines and use whatever indentation or margins that are convenient.

The shell is a program that receives a line of input typed on the keyboard, parses it into a sequence of tokens, connects programs and files together as specified by the sequence, and finally loads and executes the specified commands.
The command line interpreter is the subset of the shell that receives and interprets commands so that the shell may execute them in the correct manner.
The parser is a subset of the Command Line Interpreter, which analyzes a command string and returns a list of instructions that the command line interpreter must execute.

Command Interpreters ******************** GDB supports multiple command interpreters, and some command infrastructure to allow users or user interface writers to switch between interpreters or run commands in other interpreters.
GDB currently supports two command interpreters, the console interpreter (sometimes called the command-line interpreter or CLI) and the machine interface interpreter (or GDB/MI).
The interpreter being used by GDB may not be dynamically switched at runtime.

Generally, all commands are in free format and consist of a keyword possibly followed by one or more parameters.
A command may be in upper or lower case letters, and may be abbreviated as long as it remains unambiguous.
If the command requires parameters, and not all were entered on the same line as the command keyword, the program will prompt for the parameters by displaying the current values between square brackets:

 Course Notes for CSCI 4500 - 002
Text-oriented, or command line user interfaces are frequently called “shells.”  It is somewhat interesting that a very popular shell for the UNIX operating system was developed by an individual named Donald Shell.
You are to modify this program (or rewrite it completely, if you wish) to allow the user to select a command to be executed from a list of predefined commands that will be given in a text file, and named as the first parameter to your modified shell, which we’ll assume is named mysh.
Executing the command “mysh cmds” will first print each of the lines in the cmds file (there will be no more than 9), prefixed by a one digit integer (1 for the first command, 2 for the second, and so forth) and a blank.

The direct commands are a fixed set of commands that spawn an appropriate RSX utility to accomplish the desired function.
The command sets the UIC if one is passed as an argument on the command line, otherwise the current UIC is written on the user terminal.
The way user and system commands are handled by the command line interpreter provides a powerful method of incorporating processes as supplements to the direct commands.
