Hi Ratazong, I am a novice to perl thats why I do so much blunder. I tried another way to filter files. Instead using x2 z2 and all as variable I tried to search them as pattern. but it also having problem can you please check and tell what can I do so it may start working.

#usr/bin/perl
use strict;
use warnings;
use File::Find;
use File::stat;
my $path='e:\testfolder';

find(\&checkFile, $path);     # loop through all files in my directory

#--------------------------------- check to be applied on each file --
+-----------
sub checkFile
{
    my $fullfilename    = $File::Find::name;
    my $filesize        = stat($File::Find::name)->size;
    my $filename        = $_;
    
    # --- check for relevance based on expected filenames
    if ((! ($filename =~ /_obj_pp_comp.txt/ )) && (! ($filename =~ /ob
+j.doc/ )))    {
       return;
    }
    
    if ($filesize == 0)     {
       print ("<!-- \t\tERROR: file $fullfilename is empty. -->\n");  
+     
       return;
    }
    if (! -f $filename)     {
       print ("<!-- \t\tERROR: file $fullfilename is a directory. -->\
+n");       
       return;
    }

    analyze($fullfilename);
}
#--------------------------------- work to be done on each relevant fi
+le -------------
sub analyze
{
     my @files = $fullfilename;
        my $pat='/^x2=0.[6-9][0-9][0-9][0-9][0-9]\n';
        my $pat1='/^z2=0.[6-9][0-9][0-9][0-9][0-9]\n';
        my $pat3='/^some_t2=0.[6-9][0-9][0-9][0-9][0-9]\n';
    foreach my $file (@files)
    {
        foreach my $file1(@files)
        {
            foreach my $files2(@files)
            {
                if (($file=~/^$pat/) && ($file1=~/^$pat1/) && ($file2=
+~/^$pat3/))
                {  
                    print  "$file IS VALID\n"; 
                    system 'mv $file  E:\test\some'  
                }
              else 
                    print "not relevant\n"
            }
        }
    }
}
