Mac Terminal Download Curl

curl is a command-line tool to transfer data to or from a server, using any of the supported protocols (HTTP, FTP, IMAP, POP3, SCP, SFTP, SMTP, TFTP, TELNET, LDAP, or FILE). curl is powered by Libcurl. This tool is preferred for automation since it is designed to work without user interaction. curl can transfer multiple files at once.

Syntax:

DICT protocol: The Libcurl defines the DICT protocol which can be used to easily get the definition or meaning of any word directly from the command line.

There are two output streams generally available: standard output, and standard error. In practice, when running in a terminal, both send data to the terminal. > only redirects standard output, and curl prints the progress data to standard error. To suppress both, use one of:

As a web developer or tech enthusiast, understanding HTTP requests and how to interact with APIs is crucial, particularly when it comes to automating requests and debugging. In such scenarios, you might want to execute a quick HTML request from your terminal and this is where cURL, a free command-line tool for data transfer, comes in handy.

Client URL (cURL) lets you exchange data between your device and a server through a command-line interface (CLI). By simply specifying a server URL and the data to be sent, cURL enables diverse request forms, much like API tools like Postman and Insomnia, but directly from your terminal.

API tools like Postman and Insomnia provide an interactive user interface (UI) that allows you to make different forms of requests to URLs, for receiving and processing requests. The cURL command does the same thing, except in your terminal. cURL works on Linux, Mac, and Windows.

Without passing any flags or options, the cURL command defaults to making a GET request to the specified URL. The command returns the response body sent from the API, which would look like this in your terminal:

Instead of typing the JSON string in the terminal, you can specify a JSON file that the cURL command will use for the data option. For example, suppose you have a file called data.json with the following contents:

While API platforms usually provide intuitive interfaces for requesting and transferring data to a URL, cURL can be a great tool to use with the terminal. Here are some common use cases for the cURL command.

Using cURL on the terminal is simple, but may not be intuitive to use by every user. By providing the URL and the options needed, you can request and download data from URLs, transfer data to URLs, and more.

Atera has a terminal command that allows one to download an instance of their agent with a url. This instance automatically logs in the user into the linked Atera environment upon completion of the install through terminal.

Just a couple of things to consider, and take them with a grain of salt. Your Org hired you to be the expert on systems administration and engineering, so will be up to you to determine the risks and impacts of these things, but using curl as root on all endpoints can be very dangerous.

If you must use curl or have decided to the risks are not significant for you, you can look at tools like Installomator which has some added security features built into it, and has the same functionality as say a curl script. The repo has docs and a link to a presentation on it.

Centralizing package creation and distribution also means it is much easier to audit and troubleshoot. With something like a 10% failure rate (tossing out examples) of a curl script, good luck finding out why n number of clients are just failing. Centralizing it also helps you streamline and troubleshoot when things go wrong. So, there are other benefits than just security, or rather all of it benefits security since auditing is a part of security.

I get that some vendors make horrible installers and workflows and you might be forced into a curl model versus manually doing it by hand. However, if you don't have to do that, or can get around that I would recommend looking into such things. Personally, I use AutoPKG and have been using it for over 2 years now at my current gig. It is one of the best open source tools for macOS out there.

My point is to just make some awareness around this subject. This is also why I never use a curl script unless it is really the only option I have, and even then I would take it through security approvals before deploying it.

Without any options, curl defaults to interacting with the server using a GET HTTP request method, which is generally used for reading data only. We will cover the other HTTP request methods later in this guide.

The POST HTTP request method is very frequently used to create or update data on the server when interacting with a REST API. In order to do that, you will need to know a couple new options for the curl command:

Now you can use that file as part of your curl command. Instead of putting the data in the command, you can refer to the file by using -d @[FILENAME]. We can try it by typing curl -X POST -H 'Content-Type: application/json' -d @data.json and pressing Enter:

The PUT HTTP request method is often used to update existing data on the server when interacting with a REST API. Similar to example with POST, we want to set the method, data format, and data when using the curl command.

If you want to remove data from the server, you will likely use the DELETE HTTP request method when interacting with a REST API. This is a bit more plain compared to the previous examples. You will use -X DELETE to specify the DELETE HTTP request method and specify a specific resource URL to delete. Try it by typing curl -X DELETE and pressing Enter:

I want a key combination to launch a terminal window with wttr.in loaded. The line bindsym --release Mod4+w exec st curl wttr.in does not seem to keep the terminal window open. The window will flash on screen, closing as soon as it opens.

Curl is commonly referred to as a non-interactive web browser for the Linux terminal. Its developers, however, describe it more accurately as a tool to transfer data to or from a server, with access to a huge variety of protocols, including HTTP, FTP, SFTP, SCP, IMAP, POP3, LDAP, SMB, SMTP, and many more.

It's a useful tool for the average sysadmin, whether you use it as a quick way to download a file you need from the Internet, or to script automated updates. Curl is also an important tool for testing remote APIs. If a service you rely on or provide is unresponsive, you can use the curl command to test it.

You can download a file with curl by providing a link to a specific URL. Whatever exists at the URL you provide is, by default, downloaded and printed in your terminal. HTML is relatively verbose, so that's often a lot of text.

A query to an API endpoint is technically as simple as the most basic curl command. You point curl at the API gateway URL, and ideally, get the default response from the API. Not all APIs provide a response, but here's a good example:

You can also send commands with curl. For example, for an API behind a login screen, you can use the --form option to pass your credentials before accessing the data you need. This example isn't advisable, because your password would appear in your Bash history. However, you can configure your shell history to ignore commands preceded by a space to safeguard against this (as long as you do indeed precede the command with a blank space).

If your only interface to the Internet is through a graphical web browser, you're doomed to manual intervention almost 100% of the time. Learning to wield curl gives you new flexibility for faster interactions, automated responses, and bulk data dumps that would be unmanageable otherwise. Install curl today, and start using it for your networking needs.

I have been working on a way to check the status of Smart Plugs/Lights. I figured out how to poll the status of the light in terminal.app and receive the correct results (ON or OFF), but when trying to do this in apple script, Im getting a lot of errors/issues. The script is below that DOES work in terminal (I changed the device token/IDs for privacy). I guess its the formatting this code for AppleScript, I use Do Shell Script, and the Json fails. So anyone know how to change the format to work in an AppleScript???

No matter what changes I make to the formatting of this curl script, I cannot get it working in AppleScript. Works fine in terminal. I know AppleScript dent like double quotes, or single quotes, or this and that, no changes I can make provide we with a result :(.

curl (short for "Client URL") is a command line tool that enables data transfer over various network protocols. It communicates with a web or application server by specifying a relevant URL and the data that need to be sent or received.

curl is powered by libcurl, a portable client-side URL transfer library. You can use it directly on the command line or include it in a script. The most common use cases for curl are:

curl accepts a wide array of options, which makes it an extremely versatile command. Options start with one or two dashes. If they do not require additional values, the single-dash options can be written together. For example, the command that utilizes the -O, -L, and -v options can be written as:

In any event, just going to a web site, or using curl to get some text, is not going to install malware. It is possible to use curl to bypass some system security. So don't run a complex curl command you see posted on the internet unless you understand what it does.

I'm doing university work on the HTTP protocol and I want to explain "visually" how an HTTP connection occurs between a client and a server. To do this, I use in the Ubuntu terminal (which I have installed in VirtualBox) the command curl -v - i against an IP address, which is the IP address of the domain that I have previously obtained through the dig command. e24fc04721
