you may also want to remove line ends (chomp).

Update: note that your sample would be better given as follows to avoid external files:

use warnings;
use strict;

my $search = "Bus(Mini)\n";
while (<DATA>) {
    if ( ! /$search/ ) { print "No Match found\n"; next; }
    else { print "Found $search in main file\n"; }    
}

__DATA__
TestFile:
Bus
Bus(Mini)
Car
Van

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
