Yes, know about including the first line in python scripts:
#!/usr/bin/env python
Just tried it now under vinux VMWare machine here on my windows PC, but,
issue is just that named file just 1 and, used chmod +x 1 to, in theory
make it executable, but, if I then just type in 1 and hit enter from
command line, it seems to just lock up waiting for something - orca just
tells me there's white space appearing, but, it never executes the
python code, whereas if I type in python 1 and hit enter, then it runs
the code.
Could quite easily implement menu systems using python code itself -
python is one of my sideline focus areas, but, issue is just how to get
it to launch that script from startup for now - suppose there's the
equivalent of an autoexec.bat under linux that could add a line to to
run the script, and, then take it from there?
For example, in terms of running the arecord command, could possibly run
that in a separate thread under python using the threading module to
launch a shell command, and, then when the user made another choice from
a pseudo-menu offered using raw_input() function, then could just
terminate the thread, which should stop recording, and, then just exit
the python script, when they could then just power off - or could
possibly call something like sudo shutdown now from the python script as
well?

Bash scripts are the Linux equivalent to batch files, and indeed, they
are named .sh by convention.
The basic structure of a bash script is:
#! /bin/bash
[commands to be executed]
and once saved and made executable, you can run them by typing
path/to/script.sh
at the command line. Do note that you will need to append ./ in front
of the script name to run a script in the working directory. E.g.:
./script.sh
As for python code, if you add
#! /usr/bin/python
or
#! /usr/bin/python3
to the top of a .py source file and make it executable, you can run it
without having to invoke the python or python3 command.
In general, if I'm not mistaken, adding
#! /path/to/interpreter
to the top of a source file and making it executable works for most
interpreted languages.
And while the how is beyond my current knowledge, it is possible to
build bash scripts featuring numbered menus that can be navigated both
with the arrow keys and pressing the number corresponding to menu
options. In fact, I'm fairly certain rassbpi-config is such a script.
