wget:tldr:0a635

The command you provided is using the wget utility to retrieve webpages and their requisites from a specified URL. Here is the breakdown of the command:

wget: It invokes the wget command-line tool, which is commonly used for non-interactive downloading of files from the web.

--page-requisites: This option tells wget to download all the necessary files required to properly display the downloaded webpage. This includes stylesheets, images, scripts, and other assets linked to or referenced by the webpage.

--convert-links: When wget downloads a webpage, it will modify the links within the downloaded HTML to ensure they point to the locally downloaded files rather than the original URLs. This option helps in creating a self-sufficient copy of the webpage.

--wait=3: This option instructs wget to wait for a specified number of seconds (in this case, 3 seconds) between subsequent retrievals when downloading multiple files. It helps prevent overwhelming the server by spacing out the requests.

${https:--example-com-somepage-html}: This part is the URL of the webpage you want to download. In this example, it is https://example.com/somepage.html. Note that the ${} syntax is usually used in shell scripts to represent a variable, but here it seems to be mistakenly included in the command.

Overall, this command will use wget to download a webpage, along with all its necessary assets, modify the links within the downloaded HTML to make them local, and wait for 3 seconds between subsequent retrievals.
