The command you shared is using the HTTPie tool, a user-friendly command-line HTTP client for making HTTP requests.
Now, let's break down the command:
-
http
: This is the keyword to call the HTTPie tool. -
--follow
: This flag is used to instruct HTTPie to automatically follow any redirects it encounters while making the request. In other words, if the server responds with a redirect (e.g., HTTP 301 or 302 status code), HTTPie will automatically make a new request to the new location provided by the redirect. -
--all
: This flag tells HTTPie to display the entire HTTP exchange, including request and response headers, as well as the response body. By default, HTTPie only displays the response body. -
${https:--example-com}
: This syntax is used to pass options (URL and/or headers) to HTTPie. In this case, it's providing the URL to make the request to, which ishttps://example.com
. The${https:--example-com}
part is a way to conditionally set the URL based on whether thehttps
environment variable is set or not. If thehttps
variable is set, it will use its value as the URL; otherwise, it will default to--example-com
as the URL.
Therefore, when executing this command, HTTPie will make an HTTP request to https://example.com
, and if there are any redirects, it will automatically follow them and display the entire exchange of headers and bodies for each request and response made.
