Perl's distinct difference with other langages is the use of pattern matches and my greatest diffulty. I conduct benchmarking of new systems and gather the numerical data for internal reporting. Writing numerical regular expressions for more than one set of numbers never seems to work for me. For examle, 

iters = 320 (3.05s) aver = 9568.34 us (9603.45 us, 1.01s, 99.79%)

contains six numerical sets of numbers. I tried 

if (ln =~ /(\[+-]d) +(\[+-]d.d) +(\[+-]d.d) +(\[+-]d.d) +(\[+-]d.d) +(
+\[+-]d.d)/) { do something}

Of course this doesn't work. I have tried others with the same amoount of sucess. I would like to know how to handel numerical regularguar expressions of this type?

Thanks to all that respond.
