how to chek for the number of options in an app

[Ned]

Thanks Sina,

In your first post you said:
ls --help | wc -l
Wouldn't it only count the number of lines within the help file of the ls 
command?
The grep is a much better idea, I tried something like:
ls --help | grep -c '-'
and it returned 51 because it counted both '-' and '--', but don't know how 
to ... is there a logical or operator for situations like this?
I want to check for '-' or '--'
How to do that?

Many thanks!
Ned
