Again: AFAIK there no such thing like `bash-mode' in Emacs.

There is a `sh-mode' dealing with several kind of shells.
If `sh-mode' thinks you are dealing with a bash -- by shebang or 
suffix-- it provides for it. An alias is called `shell-script-mode'

See C-h f shell-script-mode RET

for what it does.

Didn't know that. Curious to read an example.

Well, bash might use a sh as a subset. Don't know that architecture.

Could you deliver an example of usage for that?
If you send code written for a bash to a simple sh - some may work, 
others will fail.
You are surely implementing bugs then.

What's great about a one-liner? Usually they are hard to read.
