A command line interface is where you enter text commands to a computer to make it do things. If you are on Windows and you hold the Windows key and press R, then type "cmd" (without quotations) in the dialog box there, it will open a command line terminal. Try typing "dir" (no quotations) and pressing enter. This is a simple command that shows the contents of your current directory.

There are advantages to the command line mostly based around the idea that it gives you a bit more control over what you are doing. Graphical interfaces (GUIs) sacrifice a bit of functionality for the sake of showing you what you are doing visually.

For instance, think of a folder on your computer with a hundred files in it. Say you want to rename all those files to consecutive numbers or by some other schema. In a graphical interface, you would have to click each one and rename it, but with a command line, you can navigate to that folder and tell the computer to run a simple script that renames all of them with a few simple text commands. Renaming a hundred files might take you 20 minutes in a GUI but typing out a few simple commands might take you only 30 seconds.

In non-Windows operating systems, especially UNIX- and Linux-based ones, ability to use the command line is a valuable and almost required skill, because you have access to the deepest workings of your computer.

What is full shell command line


In computing, a shell is a user interface for access to an operating system's services. It can be accessed either via command-line interface (CLI) or graphical user interface (GUI). A command line shell is the one wherein you need to enter a command on a command-prompt window to access to your operating system's services.

Cannot access web interface


I'm going to assume you can get in the command line interface. Go into the command mode (type "config t" with out the quotes ) then type "ip http server" press enter, type exit to get out of command mode and then "write memory" to save your configuration. Remember, vlan 1 on the switch MUST have a IP address for you to be able to access the web interface.

Computer command line interface discuss


Well, in the very basic sense, some of the default Windows maintenance programs have a few added functions if you run them from the command line. For example, Defragmenter can be made to defragment boot files for optimization or a variety of other specialty commands.

For optimization of the installation process, you can use a command line to repartition a USB drive as NTFS and clone a Windows install disk by giving the partition boot permissions. This is simple in the command line but would require downloading and installing a third party program to set it up in a GUI.

Some solid state drive options, such as TRIM support, are only flaggable in the command line, and TRIM is a protocol very much necessary for the smooth operation of SSDs. Hard drive functioning and indexing can be controlled at the command line level in ways that are more complex than the simple options in the Windows GUI.

Aside from the task scheduler, a variety of small scripts can be devised in the command line to eliminate small time consuming tasks such as file renaming.

Learning to use the command line is a valuable skill for any computer enthusiast.

What is the command line, and what does he do?


A command-line interface is a mechanism for interacting with a computer operating system or software by typing commands to perform specific tasks. This text-only interface contrasts with the use of a mouse pointer with a graphical user interface (GUI) to click on options, or menus on a text user interface (TUI) to select options. This method of instructing a computer to perform a given task is referred to as "entering" a command: the system waits for the user to conclude the submitting of the text command by pressing the "Enter" key (a descendant of the "carriage return" key of a typewriter keyboard). A command-line interpreter then receives, analyses, and executes the requested command.
