The whole is greater than the sum of its parts is a very famous quote from Aristotle, a Greek philosopher and scientist. This quote is particularly pertinent to Linux.
In my view, one of Linux's biggest strengths is its synergy. The usefulness of Linux doesn't derive only from the huge raft of open source (command line) utilities. Instead, it's the synergy generated by using them together, sometimes in conjunction with larger applications. This article looks at 3 open source command line HTTP clients. These clients let you download files off the internet from a command line. But they can also be used for many more interesting purposes such as testing, debugging and interacting with HTTP servers and web applications. Working with HTTP from the command-line is a worthwhile skill for HTTP architects and API designers. If you need to play around with an API, HTTPie and cURL will be invaluable.
