我想使用cron每天下载一次投资组合信息，增加了两个复杂性：

1. 它需要密码

如果我使用：

wget -U Chromium --user='e-address' --password='pass' \
    https://www.google.com/finance/portfolio > "file_"`date +"%d-%m-%Y"`+.csv

我得到的答复是：

它保存到一个名为“公文包”的文件中，而不是我要求它保存的位置（“文件”日期“%d-%m-%Y”.csv）。当我在浏览器中查看“公文包”时，它说我需要登录我的帐户，即不注意我包含的用户和密码信息。

如果我将鼠标悬停在“下载到电子表格”链接上得到的字符串添加到网址：-

wget -U Chromium --user='e-address' --password='pass' \
    https://www.google.com/finance/portfolio?... > "file_"`date +"%d-%m-%Y"`+.csv

我得到：

在这一点上，它挂着。它在此时写入的文件（'投资组合？Pid=1'）与之前使用的wget的'投资组合'文件相同。

如果我输入密码，它将继续：

非常感谢您的帮助。
