I think you question is vague, therefore I would like to summarize some
of the answers. I just gives the regexp and a short explanation of
it.
\*\* Matches two *'s
\*+ Matches one or more *'s
\*\* Matches two or more *'s...
\*{2,} Matches 2 to unlimited number of stars
\** Matches zero or any numbers of *!
All this regexps matches * which comes one after another...
Please do read the documentation of regexps once again (man perlre).
Specially the section on quantifiers!
