sudo dnf install curl

After installation is complete, verify this by typing curl in your terminal:

curl

After that, the output will appear:

curl: try 'curl --help' or 'curl --manual' for more information

Curl has been successfully installed on your server and you can use it!

Operations Using Curl

When used without any option, curl prints the source code of this URL to standard output:

curl https://example.ru

To download a file using curl, use the -o or -O option and then the file URL. The -o lowercase parameter allows you to specify the file name to save:

curl -o linux.tar.xz https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.5.3.tar.xz

When used with the -I option, curl displays the HTTP headers for this URL:

curl -I https://www.centos.org/
