Hi.

Some special characters need to be escaped in patterns. I did that here with the parens in scalar str:
Code:
#!/usr/bin/perl

# //Suppose if this is my input string

use warnings;

$str='Here we show that a virus-encoded transcription factor, viral mRNA, cellular RNA-binding protein heterodimer G3BP/Caprin-1 \(p137\), translation initiation factors eIF4E and eIF4G, and ribosomal proteins are concentrated in the same subdomains of cytoplasmic DNA factories';

open(FH,"sample.txt");
while(<FH>)
{
    if($_=~/$str/)
    # if($_=~ m|$str|)
   {
      print "matched\n";
   }
  else
  {
     print "not match\n";
  }
}
close FH;

Producing (with your data):
Code:
% ./p1
matched
not match
not match
not match

The commented if is how I often code conditional matching statements ... cheers, drl

dadadodo

dadadodo(1)                                                   General Commands Manual                                                  dadadodo(1)

NAME

       dadadodo - exterminate all rational thought

SYNOPSIS

       dadadodo [ options ] [ input-files ]

DESCRIPTION

       dadadodo is a program that analyses texts for Markov chains of word probabilities and then generates random sentences based on those proba-
       bilities.  Sometimes these sentences are nonsense, but sometimes they cut right through to the heart of the matter and reveal hidden  mean-
       ings.

OPTIONS

       dadadodo accepts the following options:

       -c, -count n
              Generate n sentences.

       -h, -help
              Show summary of options and exit.

       -html  Output HTML instead of plain text.

       -l, -load file
              Load compiled data from file ('-' for standard input).

       -o, -output file
              Save compiled data in file ('-' for standard output).

       -p, -pause s
              Delay s seconds between paragraphs.

       -w, -columns columns
              Format  output  for  a  device columns character cells in width.  If not specified, the value of the environment variable COLUMNS is
              used to determine the width.  If that variable is not defined, a width of 72 is assumed.

NOTES

       Non-option arguments are input files.  These should be text files, but may be mail folders or HTML.  MIME messages  are  handled  sensibly.
       When  no  output  file is specified, sentences will be generated from the input data directly.  However, loading a saved file is far faster
       than re-parsing the text files each time.

ENVIRONMENT

       COLUMNS
              Determines the width (in character cells) of the output if the -w, -columns option is not used.  If  not  set,  a  width  of  72  is
              assumed.
