Xcode is the development and debug environment that provides the required development files for Mac OS X and iOS applications. By installing the Developer command line tools you’ll get the macOS SDK, headers, and build tools such as the Apple LLVM compiler and Make. As a developer for Mac OS X and iOS applications, these tools make it easy to install open source software or develop applications on UNIX within Terminal.

In this article we show macOS users how to install XCode Command Line Tools from the terminal. To get started launch your terminal and run the following commands to install XCode Command Line Tools on macOS Big Sur:
