Great article EOShenzhen! A lot of useful Linux commands you demonstrated in this article.

One thing I'd like to mention, I would remove both the wallet_plugin & wallet_api_pluginfrom your configs since this exposes your private keys whenever your wallet is unlocked.

If the wallet is locked, you will only see:

However, if the wallet is unlocked, an array of key pairs will be displayed publicly for anyone to see (which is very bad to have your private keys exposed).

Solution

Launch keosdseparately and include the wallet address to your alias.
