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

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
      Do you mean something like this?
      use strict; my $string = 'ri\d+'; while (my $line = <>) { if ($line =~ m{ ( ( \Q$string\E ){3} ) }xms) { print $line; printf qq{\tMatched "$2" x 3: "$1"\n}; } }

      Why don't you post a little more of your code "calling some files"?
