Reading RSS with Standard Tools

RSS is an XML format for following updates without depending on a platform-specific timeline. A feed is just another URL, so it can be fetched, archived, and processed with ordinary tools.

Fetch a feed

Use curl to save the response before inspecting it:

curl -o feed.xml https://example.org/rss.xml

Check the document

An XML-aware tool can verify that the response is well formed:

xmllint --noout feed.xml

Keep the source URL

Store the feed URL alongside any local automation. The URL is the durable identifier; a reader application is replaceable.
