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.
