curl stands for client URL, and you use it to talk to a server (URL) in whatever protocol you specify. Its used for development as a way to test client & server communication, built into applications to perform communication between a client & a server, and its used often because its extremely portable, has great error logging, can be rate limited, and can provide a substantial amount of detail about the communication.

@curbstickle@anarchist.nexus like Facebook is a server while the app on my mobile is a client ?
Yes, facebook is running on a web server and the app (or a browser) is a client.
Yes, though really its a lot of servers.
I wouldn't worry about tools yet, I'd recommend getting a book/wiki on networking if you'd like to learn, its knowledge that builds.
It's a program to download stuff from the web. It is very flexible. You can tell it to use cookies, post form data, upload and download files. It can do basically everything a web browser does without a graphical user interface.
It is built into many software pieces. And developers love it to test stuff.
@bjoern_tantau@swg-empire.de exactly.... I wish to avoid browsers and GUIs as far as I can.... So this tickled my curiosity........
Believe me, you aren't going to get used to nor enjoy "browsing" the web with curl. It's not what you think it is.
@asudox@lemmy.asudox.dev but I can fetch the web through the terminal emulator ??
@bjoern_tantau@swg-empire.de
For that I would rather recommend a terminal browser like lynx, w3m or links2 in example. curl is more like a single web request to download one piece of raw file (an html page or an image in example). It is not meant to interpret websites and display results. If you want save webpages for offline view, then something like wget.
The modern internet isn't designed to be interacted with via a terminal.
So much of the internet today runs on JavaScript and curl won't run that
It’s an open source project that is like a Swiss Army knife for, primarily http/https, connections.
I use it daily for scripting, monitoring and automation.
@porn_was_never_the_real_issue@lemmynsfw.com l often come across this phrase, Swiss Army knife..... What does it mean actually ??
https://en.wikipedia.org/wiki/Swiss_Army_knife
A swiss army knife is a single tool that contains a number of other smaller tools that you can use in many different circumstances.
Curl is a metaphorical "swiss army knife" for connecting to computers. There are many protocols to connect to different kinds of computers running different kinds of software and curl allows one to easily connect to many of them.

@borf@lemmynsfw.com I'm sorry..... I'm on brainbin, and l'm yet to get familiar with how it works......
I still don't understand why you won't explain why you "need" to learn about curl.
You don't need to know anything at all about curl unless you're working on a technical project, and no offense, I don't think you are.
Why do you ""need"" to know about curl?
OP, please tell me more about your situation. What made you curious about this?
@borf@lemmynsfw.com tell me one thing.... Do you use the terminal on your mobile phone ??
Not these days.
Curl isn't just a command line tool, it is also a "library" which other computer software uses. Everyone's phone uses curl under the hood. Almost every electronic device that connects to something remote uses curl under the hood.
I still don't understand what you're trying to do.
@borf@lemmynsfw.com l just saw that it runs on cli, and l was wondering if it can be used as a terminal emulator.
Curl is not a terminal emulator. Unless you provide a better reason I am now assuming you are a troll.
Not a troll. Just a kid trying to figure out how to browse the web with a terminal.
This is a basic https://xyproblem.info/
I thought maybe an XY problem at first but the refusal to do any research on one's own or to reply to my repeated requests to know what they were really trying to do made me block them as posting in bad faith.
@48954246@lemmy.world well, l am a kid when it comes to computers and technology........

@borf@lemmynsfw.com l'm not a troll. I discovered it in Codeberg, and it raised my curiosity. Probably l don't have any use for it at this point of time.
Curl is very low level. It will let you download things but won't display it to you in any really useful way. It is intended to be used by other applications.
If you're looking to use it to browse websites using the terminal, you need something that uses curl in the background but displays anything you download to you in a sensible way. Two such applications are lynx and links2. These will run in your terminal.
However you may not have much fun browsing facebook or anything modern. A lot of websites require javascript, which lynx or links2 will have trouble understanding.
This is links, running on the Terminal on my phone.
@dajoho@sh.itjust.works so this is how websites look like from the terminal ?
