in reply to can any reply out with a better code than this??

can any one suggest a better code to this??
#!/usr/bin/perl -w my $string = "rid"; while (<>) { if (/($string){3}/) { print; } }
Yes, for sure:
#!/usr/bin/perl -w my $string = "rid"; while (<>) { if (/($string){3}/) { print; } }
and, arguably:
use strict; my $string = 'ri\d+'; while (my $line = <>) { if ($line =~ m{ (?: \Q$string\E ){3} }xms) { print $line; } }

    the code above mentioned is not printing the matched content
      Sorry, asdfghjkl, I confused you by changing the string. Try running it with ri\d+ri\d+ri\d+ for a match. That was meant to emphasize the use of \Q...\E.
        can u suggest me a code from taking both the things from terminal itself....can i print out the matched content with my code properly.i had justed tested out for a few cases like calling some files.etc.......whether it would work for any case like that so that it need to match 3 consecutive times as per the contents of $string
