Introduction to curl in Linux with Examples

The curl command is one of the most powerful and useful tools that are used by web developers as well as by PHP programmers and System Administrators. Most commonly, it is used to transfer data between remote and local systems.

Through this command, we can access or download content from a website without a browser. It is also useful for testing APIs, troubleshooting network-related issues, uploading files, and posting data to the website. cURL is an inbuilt command line utility that runs on most Linux/Unix-based systems. Microsoft even announced that the curl will become a standard component of Windows with version (Windows 10 build 17063).
