Convention/standard for naming files, functions and variables

Is there any convention for naming files?  I understand that in most cases 
letters are lowercase but I can't figure out when to use underscores and 
when dashes.  I'd also like to know how to name functions in shell scripts, 
which environment variables should be lowercase and which should be 
uppercase.  If there is a convention or a standard about this stuff, I'd 
like to see it too.
