Hi, this mailing list is very kind, and as part of that kindness
I want to offer you some kind advice.

First, no mailing list will have the
patience to teach you every feature of a programming
language, one question at a time.

So, here are two excellent websites for self-learning about shell
scripting:

https://www.shellcheck.net/

and

http://mywiki.wooledge.org/BashGuide
http://mywiki.wooledge.org/BashFAQ

wooledge.org will inform you, and shellcheck.net will correct and
advise improvements to any code that you paste into it.

Second, a good place to ask for help is on this mailing list
specifically for questions about shells and scripting:
  help-bash@gnu.org
which has archives here:
  https://lists.gnu.org/archive/html/help-bash/

Most of the people who give answers on that list are
extremely knowledgable about shell scripting.
That's not the case here. Shell scripting is hard,
and people who haven't spent a lot of time digging into
all the details often do not give good advice. The same is true
of the web, a lot of public shell examples are suboptimal
in some way.

Here's the answer to your question:
