In the future, it's better if you post questions to the mailing list at
email@example.com; I don't always have time to respond.
The easiest way to do what you want may be to log in using your browser,
and then tell Wget to use the cookies from your browser, using
- --load-cookies=<path-to-browser's-cookies>. Of course, this only works
if your browser saves its cookies in the standard text format (Firefox
prior to version 3 will do this), or can export to that format (note
that someone contributed a patch to allow Wget to work with Firefox 3
cookies; it's linked from http://wget.addictivecode.org/, it's
unoffocial so I can't vouch for its quality).
Otherwise, you can perform the login using Wget, saving the cookies to a
file of your choice, using --post-data=..., --save-cookies=cookies.txt,
and probably --keep-session-cookies. This will require that you know
what data to place in --post-data, which generally requires that you dig
around in the HTML to find the right form field names, and where to post
For instance, if you find a form like the following within the page
containing the log-in form:
<form action="/doLogin.php" method="POST">
<input type="text" name="s-login">
<input type="password" name="s-pass">
then you need to do something like:
$ wget --post-data='s-login=USERNAME&s-pass=PASSWORD' \
--save-cookies=my-cookies.txt --keep-session-cookies \
(Note that you _don't_ necessarily send the information to the page that
had the login page: you send it to the spot mentioned in the "action"
attribute of the password form.)
Once this is done, you _should_ be able to perform further operations
with Wget as if you're logged in, by using
$ wget --load-cookies=my-cookies.txt --save-cookies=my-cookies.txt \
