3. Curl Command may be used to slow down the download of files.
File downloads may suck up a lot of your bandwidth and make your surfing experience sluggish. Thankfully, by using the —limit-rate option followed by speed, you may define a transfer rate. The required speed may be provided in kilobytes (k), megabytes (m) or megabytes (M), or gigabytes (g) or gigabytes (g) or gigabytes (g) or gigabytes (g) or gigabytes (g) or gigabytes (g) or gigabytes (g) (G).
—limit-rate [value] [URL] $ curl
The command below, for example, restricts the download pace of the Node.JS binary file to 200 Kbps.
—limit-rate 200k -O curl https://nodejs.org/dist/v16.14.2/node-v16.14.2.tar.gz
4. Use the Curl Command to resume a broken file download.
Downloads are often stopped for a variety of reasons, including network outages. Curl’s -C option may be used to restart a download from where it was stopped.
In the case that the network is disrupted, you may, for example, continue the download of git.
curl -C – -O $$$$$$$$$ http://yourdomain.com/yourfile.tar.gz
5. Using the Curl Command, get the HTTP Headers of a URL
HTTP headers include information such as the webserver type, user agent, HTTP version, content type, and more that are included in HTTP requests.
Use the -I option to get the HTTP header of a URL, like shown:
$ curl -I https://www.google.com Fetch HTTP Headers with Curl

Using Curl and the -u option, you may upload and retrieve files from any FTP server.
