Or more cryptically, but much faster as it's a single regexp scan and no
intermediate array is created:

def find_share(sharelist, match)
  return $1 if /^#{Regexp.escape(match)}$\n(.*?\n)\n/m =~ sharelist + "\n"
  nil
end

puts find_share(sharelist, "\\\\testserver2\\BACKUPTEST")

Note that ^ and $ match start and end of line anywhere within the string,
not just the start and end of the string.

Here find_share() also strips off the sharename, leaving just the users and
their rights, but you can change this by moving the capture parentheses in
the regexp if you wish.
