Ubuntu

Also, you can get a hint at the contents using the file utility, if available. If the result is "HTML document text" (or something alike) you didn't download an archive but a webpage.

The op already stated they cannot open it. It is a partial download of a rar file, as the op said. HTML error messages are not 44k in size. It is a partial download as the posted.

I believe he is trying to open it using RAR software (whatever that's called on Ubuntu).

If the server returned an error (i.e. 404 or authentication error) it would likely be the same HTML page you would see in a web browser. That could be any size.

In any case is Winnie the Pooh film free?

Just for fun I tried the download like the OP. It is an HTML "error message", 44k in size, telling the user that there's no valid login and that you should provide credentials (because there's no session cookie).

@LinuxLearner: the --user and --password options only work with FTP or HTTP Basic Authentication, but not with Form-based (eg: input boxes) / session cookie authentication. For that you'll have to resort to screen-scraping, or create a file with a valid cookie, and supply that via the --load-cookies parameter.
