_underscore as variable name prefix

[icy]

Though it's part of my coding style, sometimes I see it's very annoying. Yes I admit that :P in some long script I strictly follow the convention, but I also often break the rule.

Is that good to deprecate that one?

For me, it's a 👍 for deprecating this one.

The main purpose as describe in the style guide can be archived with ${this_is_a_variable}. That feels more natural and iconsistent with other guide like Google.

The only software that I notice so far, which use _ in variable name is https://developer.apple.com/library/archive/technotes/tn2228/_index.html#//apple_ref/doc/uid/DTS40007991-CH1-SUBSECTION15

Thanks @cuonglm. Let me fix that. My new script would follow new style and I don't think I need to rewrite all past scripts.

Btw, there is some bash formatter :D

I have a (tough) chance to look at some of my code I wrote 18 years ago. Now I know where my _ comes from. It's inspired by Python coding style https://docs.python.org/2/library/inspect.html =))

I learnt Python before I learnt Bash :D
