Wget can’t detect filename when 301/302 redirections. For example, to download the MySQL source code from http://www.mysql.com/downloads/mirror.php?id=408580

wget http://www.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.25a-linux2.6-x86_64.tar.gz/from/http://cdn.mysql.com/

The file will be save as index.html

wget http://cdn.mysql.com/Downloads/MySQL-5.5/mysql-5.5.25a-linux2.6-x86_64.tar.gz

The file will be save as mysql-5.5.25a-linux2.6-x86_64.tar.gz

but the first url is only a redirection for second URL as it is shown in:

curl -I http://www.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.25a-linux2.6-x86_64.tar.gz/from/http://cdn.mysql.com/

How can wget save http://www.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.25a-linux2.6-x86_64.tar.gz/from/http://cdn.mysql.com/ as “.tar.gz” automatically (without using -O argument)?

    Try the following command:

    wget --content-disposition http://www.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.25a-linux2.6-x86_64.tar.gz/from/http://cdn.mysql.com/

    When this is set to on, the experimental (not fully-functional) support for “Content-Disposition” header is enabled. This can result in extra round-trips to the server for a “HEAD” request and is known to suffer from a few bugs, which is why it is not currently enabled by default.

    This option is useful for some file-downloading CGI programs that use “Content-Disposition” header to describe what the name of a downloaded file should be.
