What is Command Line Interface?

A command-line interface (CLI) is a type of user interface that allows users to interact with a computer or other device by typing commands into a text-based terminal window. A CLI can be used to execute programs, configure systems, and manage files on the system. The use of a CLI allows users to quickly access and perform tasks in the operating system without having to navigate complex graphical user interfaces (GUIs).The primary advantage of using a CLI is its speed; as all commands must be typed manually, it is faster than navigating through menus and windows in a GUI. This makes it ideal for performing specific tasks quickly such as searching for files or editing configuration settings. Additionally, CLIs are generally easier to learn than GUIs since fewer options are present. They also provide more flexibility when working with multiple applications at once since different commands can be combined together in order to automate tasks. Another advantage of the command line is its ability to work within scripts which allow multiple commands to be written at once and executed sequentially. This enables processes that would otherwise require manual intervention such as backups or data manipulation operations on large datasets. Scripts can also help cut down on human errors when executing repetitive operations over long periods of time due to their automated nature. Despite these advantages, there are some drawbacks associated with using CLIs including lack of feedback when entering incorrect commands and difficulty troubleshooting errors if something goes wrong during execution. Additionally, they require more technical knowledge than GUIs which may make them inaccessible for novice users who don’t have the necessary skillset required for understanding how they work properly.
