I can't test it on my laptop since it doesn't have a wget utility, but it should come close to doing what you want. If it doesn't, please show us the output the above wget command produces (in CODE tags), so we can see what the data you're trying to process really looks like.

Please also get into the habit of letting us know what operating system and shell you're using whenever you start a thread in this forum. The utilities (and the options they support) vary from system to system and shell features vary from shell to shell. Telling us details about your environment helps us provide you with suggestions that will work in your environment.

And, please use CODE tags (not ICODE and not QUOTE tags) for sample full-line and multi-line input, output, and code segments. Use ICODE tags when displaying partial-line sample input, output, and code segments in-line with other text.
