I have a Bourne Shell script that has several functions in it, and allows to be called in the following way:

my.sh <func_name> <param1> <param2>

Inside func_name() will be called with param1 and param2.

I want to create a "help" function that would just list all available functions, even without parameters.

The question: how do I get a list of all function names in a script from inside the script?

I'd like to avoid having to parse it and look for function patterns. Too easy to get wrong.

Thanks, Alex
