If you receive an error message when you try to download a file with curl that the curl command was not found, the curl package is not installed on the CentOS computer.

This article provides instructions on how to install and use curl commands on CentOS 8.

Install curl on CentOS

The Curl package is available in the standard CentOS 8 repository. To install it, run the following command:

[linuxidc@localhost ~ / www.linuxidc.com] $sudo dnf install curl

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

[linuxidc@localhost ~ / www.linuxidc.com] $curl

The output should look like this:

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

Use curl

When used without any options, curl prints the source code for a given URL to standard output:

[linuxidc@localhost ~ / www.linuxidc.com] $curl https://www.linuxidc.com

To download a file with curl, use the-o or-O option, and then use URL to point to the file.

The lowercase-o option allows you to specify the name of the saved file:

[linuxidc@localhost ~ / www.linuxidc.com] $curl-o linux.jpg https://www.linuxidc.com/logo/linuxidc.jpg

Uppercase-O saves the file with the original file name:

[linuxidc@localhost ~ / www.linuxidc.com] $curl-O https://www.linuxidc.com/logo/linuxidc.jpg

When used with the-I option, curl displays the HTTP header for a given URL:

[linuxidc@localhost ~ / www.linuxidc.com] $curl-I https://www.linuxidc.com/HTTP/1.1 200 OKDate: Sat, 15 Feb 2020 07:37:39 GMTContent-Type: text/htmlConnection: keep-aliveVary: Accept-EncodingCache-Control: max-age=60Last-Modified: Sat, 15 Feb 2020 07:33:07 GMTETag: W / "80bb522ad2e3d51:0" Vary: Accept-EncodingX-Frame-Options: SAMEORIGINX-Via-JSL: 0b3d685 cache 2.4.6 diskSet-Cookie: _ _ jsluid_s=117b674ea22b6333f3c2075297cb0217; max-age=31536000; path=/; HttpOnly SecureExpires: Sat, 15 Feb 2020 07:38:39 GMTX-Cache: hit
