The command "rich ${filename-md} --export-html ${filename-html}" seems to use a tool called "rich" to convert a markdown file to an HTML file.

Here's a breakdown of the command:

• "rich" is the name or location of the tool/command being executed.
• "${filename-md}" is a placeholder for the name of the markdown file you want to convert, with "-md" denoting the file extension.
• "--export-html" is an option or flag provided to the "rich" tool, indicating the intention to export the markdown file to HTML format.
• "${filename-html}" is another placeholder for the desired name of the HTML file that will be generated, with "-html" indicating the file extension.

In summary, when you run this command, the "rich" tool will convert the specified markdown file to an HTML file, with the resulting HTML file having the name you provided for it.
