Well, you double posted this, but I'll answer here.
Your simplest bet is to not bother piping anything, just use links (a text based browser, in case you didn't know). If you run it like so:
links -dump file.html
This will strip all HTML and print the plain text file to terminal, so you can pipe that out to a file and off you go.
Hope that helps.

As noted. I believe the Software forum was the most appropriate forum, so I'll close this thread.
Please post follow ups at:

In the future, please choose the most appropriate forum to place your question in, and place it one time in only that forum.

Thank you!
