Dear All, Thanks for your concerns and suggestions. The idea of $mpath i.e., when I execute this command: `/vobs/package134/inttools/modules/unixtools/srce/whichPath $m :: I will get the output as /vobs/package183/psappat/modules/<module name, that is having the $m value in the foreach loop>, So now I want to cd into this module, and then cd into confm folder, Here in this path/location, My intention is to check whether post_REFERENCED_to_EXPERIMENTAL file exists? and if so, find the link attached to this file. My concern is still I am not able to CHDIR into module. Please suggest. Modified Script: 
use Cwd qw(chdir);

open(LS, "/home/raghvens/52xxmodulelist.txt") or die $!;

@modlist = <LS>;
@mpath = " ";
foreach $m (@modlist)
{
   
   print "\nProcessing $m .. \n";

   $mpath = `/vobs/package134/inttools/modules/unixtools/srce/whichPat
+h $m`;
   print "\nModule Path is $mpath \n";

   chomp($mpath);
   $path = `chdir $mpath`; # or die "Can't cd into module path:$mpath 
+\n";
   
   print "\nCurrent Path is $path";

   if(! chdir($mpath)){
    print "\n cannot change the working directory \n";
    }

   `chdir confm`;

   $file = "post_REFERENCED_to_EXPERIMENTAL";
   @output = system ("ls -l $file");
   print "YES, Link is present" if $_ =~ /\-\>/ ; 
}
