  2. Or use curl, where it's the default behaviour.

    curl http://www.google.com/

    http://curl.haxx.se/

  3. There are other methods you can use instead of wget and curl:

    You can use lynx:

    # lynx -source http://www.google.com

    w3m:

    # w3m -dump_source http://www.google.com

    and libwww-perl comes with a handy program called GET (as well has HEAD and POST, which do what you think they do)

    # GET http://www.google.com

  4. This is how I did it:

    URL='http://wordpress.org/extend/plugins/akismet/'
curl -s "$URL" | egrep -o "http://downloads.wordpress.org/plugin/[^']+" | xargs wget -qO-

  5. Just to add another option: I often use lwp-request, from libwww-perl, for this. It outputs to STDOUT by default and is more likely than curl to be installed on the systems I use (your situation my vary).
