Fetching Data Using curl Command
One of the most common use cases of `curl` is fetching data from a URL. This could be a simple HTML page, a file, or any resource accessible via a URL. To fetch a web page using `curl`, you simply provide the URL as an argument:
curl https://example.com
This command will retrieve the HTML content of the specified URL and display it in the terminal.
curl https://www.w3wiki.org
This should display the content of the URL on the terminal. The URL syntax is protocol dependent and multiple URLs can be written as sets like:
curl http://site.{one, two, three}.com
URLs with numeric sequence series can be written as:
curl ftp://ftp.example.com/file[1-20].jpeg
Progress Meter: curl displays a progress meter during use to indicate the transfer rate, amount of data transferred, time left, etc.
curl -# -O ftp://ftp.example.com/file.zip
curl --silent ftp://ftp.example.com/file.zip
If you like a progress bar instead of a meter, you can use the -# option as in the example above, or –silent if you want to disable it completely.
