Bash does not have the features you're looking for. I'm not aware of a
third-party utility to use with Bash that has them either (getopt is

The Python core module called argparse does much of what you want and is
rich with features and is easy to use, easy to extend and code to
supplement its functionality (for example, to do unusual mutual exclusion)
is easy to write. By far the most sensible thing to do if you are going to
use Python to write your argument processor would be to write your whole
program in Python. But it's conceivable that you could process your args in
Python and write the rest of your program in Bash. But don't do that.

Don't assemble an engine using a very good pair of pliers when a very good
socket wrench is within a hand's reach.
