How to add parameters with specified prompt

Question

I want to write a bash shell script, it can accept parameters, and the parameter has prompt, example,

./test.sh --version=1.0

value 1.0 is the real parameter for my shell, and --version= is the prompt

is there any easy way to do it like this?

Answer 1

You should have have a look at man(1) getopt.

Answer 2

Depending what you mean by "easy" - using getopts should work. A bit of typing, but... Here are some examples to get you started:
