    I don't really understand what you are asking for here. In order to make the most of the site, please take a look at How (Not) To Ask A Question. Thanks!
    Now, given your post, I am guessing you may find (Count the number of lines in a file) useful. It is a little bit obfuscated, but it can be run straight from the command line. If this doesn't help, could you clarify what you mean by "elements"?

    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.
