That's a bit vague... please see How do I post a question effectively? and perhaps you could explain a bit more about what you're trying to do and what you have tried so far.

Anyway, if you really just want a count of the existing UNIX groups, see getgrent (note: apparently the online doc for this version isn't showing up, but try the command perldoc -f getgrent), here's one quick way:

my $count = 0;
$count++ while defined getgrent;
print "$count\n";
