Application Programming Interface (API) is a set of commands, functions, protocols, and objects that programmers can use to create software or interact with an external system. It provides developers with standard commands for performing common operations so they do not have to write the code from scratch.
Operating system APIs are typically integrated into the software development kit for the corresponding program. For example, Apple's Xcode IDE allows developers to drag and drop elements into an application's interface. It also provides a list of available functions and includes syntax highlighting for known elements and commands. Operating system APIs have a robust set of features.
The dir command displays information about files and directories, and how much disk space is available. By default, it displays the name, size, and last modification time of every file in the current directory.
