cURL on terminal , command-line with clear example

cURL

cURL is a command-line tool used to transfer data to or from a server. It supports various protocols such as HTTP, HTTPS, FTP, and more. cURL can be used in the terminal to make requests to web servers, download files, and more. It can also be used to send data to a server, such as uploading a file. Some common cURL commands include curl -X GET [URL] to make a GET request to a URL, curl -X POST [URL] -d [data] to make a POST request with data, and curl -O [URL] to download a file from a URL.

Here are some examples of using cURL in the terminal

curl -X GET https://www.example.com

This will return the HTML source code of the website's homepage.

Another example of using cURL to make a POST request with data, you could use the following command:

curl -X POST https://www.example.com/submit -d "name=value&field=value"

This will send a POST request to the "submit" page on the website with the data "name=value&field=value" in the request body.

And an example of using cURL to download a file from a URL:

curl -O https://www.example.com/downloads/file.zip

This will download the file "file.zip" from the "downloads" directory on the website "example.com" and save it in the current directory.

To send a GET request and save the response to a file, you can use the following command:

curl -X GET https://www.example.com -o response.txt

This will save the response from the website in a file called "response.txt" in the current directory.

To send a GET request with a specific HTTP header, you can use the following command:

curl -H "Authorization: Bearer YOUR_TOKEN" https://www.example.com

This will send a GET request to the website with an "Authorization" header set to "Bearer YOUR_TOKEN".

To send a GET request and follow redirects, you can use the following command:

curl -L https://www.example.com

This will send a GET request to the website and follow any redirects that the server returns.

To send a GET request and show the response headers in addition to the response body, you can use the following command:

curl -i https://www.example.com

This will show the response headers, such as the "Content-Type" and "Status" headers, in addition to the response body.

These are just a few examples of the many things you can do with cURL, and many more options are available.
