But I don’t want to match 12,2, or 234432 53. I want to match whether string contains 1 2 OR 1,2 OR 1,2,3 OR 1 2 3 Or any such combinations. And I think this reg. exp. is doing that job.

Your regex will match 1,2 or 1 2, but *not* 12,2 or 234323 53 if ($trig_np =~ m/ \d+ [,\s] \d* /x) is much more correct This e-mail and any files transmitted with it are for the sole use of the intended recipient(s) and may contain confidential and privileged information.
