wget -P /path/to/directory <file_url>

You can also use the -O option to specify the output filename:

wget -O output-file-name <file_url>

To download multiple files, you can create a text file containing the list of URLs and use the -i option to download them in batch:

wget -i urls.txt

You can also use wget to download a website, including all of its assets (HTML, images, etc.):

wget --mirror --convert-links --page-requisites --no-parent <website_url>

This will create a complete mirror of the website in the current directory.
