Question: I want to the foreach command seems more delicate. How to do that?

  • foreach i in {1,1.1,...,2.8,2.7,2.6,2.5,2.4,2.3,2.2,2.1,2,1.9,1.8,1.7,1.6,1.5,1.4,1.3,1.2,1.1,1} can be abbreviated to foreach i in {1,1.1,...,2.8,2.7,2.6,...,1}. P.S. It is a cool animation, so +1. ;-)

4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset. My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials.
