I'm wondering if I can use lynx with the -post_data option to log into my
eBay account with one bash shell command.

I can't find any detailed docs on using this option, only that the data
has to be "properly formatted."

Can anyone show me where there is more info on this or provide an example?

Thanks,
Ed
