Like curl or this website specifically?
curl is a CLI tool used primarily to interact with webservers.
It can do much more than that, but its unclear what kind of an explanation you're seeking.
So it's basically a terminal emulator ?
Not quite the right way of thinking about it.
curl is a program that can be used from a terminal.
Servers are often interacted with via URLs.
curl is just one of many tools for interacting with them.
If you have access to a terminal with curl installed I would suggest running man curl and having a read of the output.
Alternatively it can be read here:
I've see your other posts now and I've come to the conclusion you are trying to figure out how to browse the web via a terminal.
In the biz we call this an https://xyproblem.info/
You were never going to get a satisfying answer with your question.
A better one would have been "how do I browse the web with a terminal"
And people would have directed you to search for things like "terminal browser"
Curl is a tool used to ask servers and websites for information from the command line. It outputs this information to you directly as stdout instead of just downloading a file to a given location. You can use pipes and redirections to work with this though
Usually it's used by developers.
Personally, I use it to get files from github or websites. If can also be used to send stuff to a server.
It's a very simple tool that just sends the request and gives the answer. If you were to point it at a website you'd get back the code a browser would normally use to make the website on your end.
