 The command will create a compressed file ''request.txt.gz''. Afterward, the ''curl'' command shall read:
 <code bash>
-curl -v --data-binary @request.txt.gz "Content-Type: application/x-www-url-form-urlencoded" -H "Content-Encoding: gzip" -X POST http://server.tld/
+curl -v --data-binary @request.txt.gz "Content-Type: application/x-www-form-urlencoded" -H "Content-Encoding: gzip" -X POST http://server.tld/
 </code>
 where:
   * ''-v'' turns on verbosity,
   * ''--data-binary @request.txt.gz'' will send the ''request.txt.gz'' file as the request body (mind the ''@'', it is necessary),
-  * the request ''Content-Type'' is set to ''application/x-www-url-form-urlencoded'' indicating that the ''request.txt.gz'' file contains POST key-value data,
+  * the request ''Content-Type'' is set to ''application/x-www-form-urlencoded'' indicating that the ''request.txt.gz'' file contains POST key-value data,
   * the request ''Content-Encoding'' is set to ''gzip'',
   * the request will be sent to ''<nowiki>http://server.tld/</nowiki>''

+The following command:
+<code bash>
+curl -fLOsS https://www.deb-multimedia.org/pool/main/d/deb-multimedia-keyring/deb-multimedia-keyring_2024.9.1_all.deb
+</code>
+will download the binary file ''deb-multimedia-keyring_2024.9.1_all.deb'' to the current directory by using ''fLOsS'' as command-line parameters passed to ''curl''.
+The parameters ''-fLOsS'' carry the following meaning:
+  * ''-f'' makes curl fail in case there are errors and to not output any document,
+  * ''-L'' means to follow any redirects,
+  * ''-O'' tells curl to save the the body to the current directory,
+  * ''-s'' makes curl silent,
+  * ''-S'' makes curl show an error in case the download fails (this combines with ''-s'', as in, be silent if no fail)
