/dev/tcp is a bashism. It's not a real (kernel-provided) device.

Why do people like cURL? I've regularly found it to have stupid defaults compared to wget. Is it because it's default on Mac and wget isn't?

cURL is worth learning in my experience because it is bulletproof, ubiquitous, fast, highly-configurable, and comprehensive. No other option listed in here are all of those things, though they are all easier to use. But start talking about SOCKS5 proxies or FTPS and all of a sudden you have to start monkey patching your (pretty) tool or, you know, learning curl. Seriously how often are you guys performing PUTs and DE…

I didn't realize there was such a discrepency in proxy functionality, that's exactly what I was looking for.

`curl --head http://google.com` is useful just to get the response headers back.

I knew 8 of the 9, but the one I didn't (testing virtual hosts) was worth the cost of reading the entire article. Thanks.

I just tweak my /etc/hosts to do this.

Curl is great to have, but remembering all the options flags is a pain. Nowadays I use: Chrome: "Postman" extension Firefox: "REST Client" addon ...both great utilities for creating and saving any HTTP request you need.

man curl

Real HTTP from the command line is 'telnet localhost 80'.

'nc localhost 80' FTFY

Actually, you broke it. telnet sends CRLF line breaks like you're supposed to. nc will just send LF. A strict web server won't talk to you.

I'd be interested to know exactly what you mean (I usually don't really get sarcasm). It seems that you think this advice is useless, or that people never use the command line, or something, but I don't really know what. Could you be more specific? I find it useful to understand different points of view. Thanks

Site is "Hacker News", not "How-tos for dummies", last time I checked. Do we really need this kind of stuff in home page? Hardly so. What about an article on how to create a three columns layout with CSS? Or how to edit a file using a text editor? Come on... how to use curl? Really?

Seeing that 200+ people upvoted, it would suggests that enough people found it useful.

I will admit that I am not familiar with curl and I found this helpful and enlightening. If you don't find it useful, then just move on. We come to HKN to learn about the other aspects that we are not familiar with. Just be mindful that not everyone have the same expertise.

I would strongly suggest HTTPie for the majority of these tasks: https://github.com/jkbr/httpie

Here's a pitch for another nice one: http://echohttp.com/
