The ipgw cli can no longer work normally due to the platform update. It needs to be adapted first, so I'll close this pr.
FYI, #36

If we're going to integrate scheduled automatic login and logout into ipgw cli, we'd better make ipgw cli a daemon and execute specific scripts containing online tasks at night.

However, I think it is best to use external job schedulers, such as cron, to provide higher freedom, and let ipgw cli continue to follow the philosophy: make each program do one thing well.

Just found the tool dysfunctional. Sad.

In normal use, we have to use pc to download at night, so I think it's ok to create a screen and run it all night.
Under normal circumstances, there are not download tasks every day, so I don't think we have to treat it like a scheduled task that have to run everyday. It's better to run manually when you need.
(The daemon thing is out of my capability. Waiting for further update )

Anyway, this have to wait until the cli fixed.

PRs for adaption are welcomed.😍
