Learn what a command handler is

Do you know what a command handler is? If not, the answer is that it is an operating system that processes and executes users’ commands.

If you want to get more information about the command handler, then you should read this article. This is because you will not get much information about this computer term.

That is why today I thought why not be given complete information about it so that no doubt remains in your mind. So let’s start without delay what is the command processor know in detail on the topic.

What is a command handler?

This is the part of the operating system that receives and executes commands from the operating system. Every operating system has a command processor.

When one command prompt is displayed, then this command handler is waiting for any one command. When a command is entered, the command handler analyzes that command’s syntax to ensure that the command is valid or not, and then executes that command or issues an error warning.

Whereas in operating systems that have a graphical user interface, this command handler interprets mouse operations and executes appropriate commands.

Another name for the command processor is the command line interpreter and

A command handler is such a program (written in assembler language, PL/1 , or assembled and linked into a loader) that receives control when a user enters a command name into a terminal.

It is given control over Terminal Monitoring Program (TMP), a program that provides an interface between terminal users and command handlers, and has access to many system services.

The main difference between a command handler and other programs is that when a command handler is called, it is called a command handler. A command handler parameter passed list (CPPL) that provides program access to caller information and other system services.

Command processors must communicate with the user in the device, as well as respond to abnormal terminations and interruptions of attention.

Command handlers very easily recognize the names of subcommands entered by a terminal user, then load and pass control to the appropriate subcommand handler.

What is a command line interpreter

A command line interpreter is a program that allows you to enter commands and then execute those commands in the operating system. Or you could say it’s a command interpreter literally.

A program in which a graphical user interface (GUI) such as buttons and menus is controlled by a mouse, while in a command line interpreter, lines of text are accepted as commands from the keyboard and then converted into functions. Only the operating system can understand it.

A command line interpreter program is generally referred to as a command line interface. It has another name CLI, command language interpreter, console user interface, command processor, shell, command line shell, command interpreter, and

Why is a command line interpreter used?

If it can be controlled in a PC with easy-to-use graphical interface applications, you must be wondering why someone would need a command line to enter commands. Well, there are three main reasons for this, we will know about them.

The first reason is that you can automate commands. There are many examples of this, such as a script that always turns off certain services or programs when the user first logs in.

The second is that if you want, you can copy the similar file format, so you don’t have to go from one place to another again and again. All of these things can be done quickly and automatically using commands.

Another benefit is that with the command line interpreter, you get direct access to the functions of the operating system. Advanced users may prefer the command line interface if they want, as this short and powerful access provides them with the convenience they need.

On the other hand, new users or inexperienced users may have problems with this, as it requires experience. The commands available in this are not as common as they were in the menus and buttons.

The third advantage is that we can use command line interpreters when we have a large number of commands and options to control the operating system, but we do not understand how to do it.

The operating system’s GUI software may simply not be built in to use these commands. Plus the command line interpreter helps you use some, but not all, of these commands. Commands to use together.

This makes it more useful on systems where you have fewer resources to run graphic programs.

Talking about first Windows XP and Windows 2000 In the United States, a special diagnostic tool also called Recovery Console acted as a command line interpreter and performed various troubleshooting and system repair tasks.

macOS has its command line interface called Terminal.

It has often been noticed that the command line interface and the graphical user interface are included in the same program. When such a situation occurs, it is usual for the interface to support some functions that are not available in others.

This is often the part of the command line where more features should be included because it provides raw access to the application’s files and is not limited to what the developer chooses to include in the GUI.

Why is the command interpreter different from the kernel?

It reads and executes commands from the user or command file, usually by turning them into one or more system calls. It is usually not part of the kernel because the command interpreter is subject to change.

What is the purpose of command interpreters?

Command interpreters have a large number of commands and inquiries available for various tasks. In addition, typing is much faster than clicking as is the case with the GUI.
