The command rsstail -1 -u ${url} is used to retrieve and display the most recent RSS feed item from a specified URL.

Here's the breakdown of the command:

• rsstail is the name of the command-line tool that is being executed.
• -1 is an option that instructs rsstail to only display the latest feed item. If there are multiple items in the RSS feed, this option ensures that only the most recent one is shown.
• -u ${url} is another option that specifies the URL of the RSS feed that you want to retrieve. ${url} is a placeholder that should be replaced with the actual URL.

So, when you execute this command with the specific URL you want to monitor, rsstail will fetch the latest item from that RSS feed and display it in the terminal/console.
