in reply to parsing a file to get the count alone

Maybe you need something like this:

#!/usr/bin/perl use strict; use warnings; local $/ = "\nGenerating"; while(my $entry = <DATA>){ my ($table,$count) = $entry =~ /Summary of ([^\s]+).*(\d+)/s; print $table,": ",$count,"\n" if $count > 1; } __DATA__ Generating Summary of table_1 (count(*)) 1 Generating Summary of table_2 (count(*)) 2

    I guess that is (close to) what Anonymous Monk wanted.

    Just a small remark, [^\s]+ can be written /S+ in your regex.
