        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 thehttpsenvironment variable is set or not. If thehttpsvariable is set, it will use its value as the URL; otherwise, it will default to--example-comas 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.
