How to Add a Header to a curl Request
curl is one of those great utilities that's been around seemingly forever and has endless use cases. These days I find myself using curl to batch download files and test APIs. Sometimes my testing leads me to using different HTTP headers in my requests.
To add a header to a curl request, use the -H flag:
