Attach a header to an HTTP request with cURL

curl

$ curl --header "${header}" ${url}

try on your machine

The command curl --header "${header}" ${url} is utilizing the curl command-line tool to make an HTTP request to the specified URL (${url}). It includes a custom header in the request, which is passed through the ${header} variable.

Let's break down the command and its components:

curl: It is a command-line tool used to send HTTP requests and retrieve data from web servers. It supports various protocols, including HTTP, HTTPS, FTP, etc.
--header "${header}": This specifies a custom header in the HTTP request. The ${header} here represents a variable that should contain the desired header value. It is enclosed within double-quotes ("${header}") to handle any potential spaces or special characters in the header.
${url}: It represents a variable containing the URL to which the HTTP request will be sent. The URL should be specified without any quotes, as the shell will handle any necessary escaping automatically.

By combining these components, the curl command sends an HTTP request to the specified URL with a custom header included in the request. The value of the header is determined by the ${header} variable.
