File 1 
EC:1.1.1.42    isocitratedehydrogenase
EC:1.1.1.44    6-phosphogluconatedehydrogenase
EC:1.1.1.49    glucose-6-phosphate1-dehydrogenase

EC:1.1.1.44    6-phosphogluconatedehydrogenase
EC:1.1.1.49    glucose-6-phosphate1-dehydrogenase

EC:1.11.1.9    glutathioneperoxidase

Code that I have written 
#!/usr/bin/perl
$dir = "C:/Perl/bin/kegg";
open (FILE3,">>","$dir/keggdifference1.txt"); 
open (FILE4,">>","$dir/keggdifference2.txt"); 
 
open (FILE,"<","$dir/common.txt");
while (<FILE>) {
    chomp ($file=$_);
    @array =split (/\t/,"$file");
#print "$array[0]\n";
}    
open (FILE1,"<","$dir/bacillus1.txt");
while (<FILE1>) {
    chomp ($file1=$_);
    @array1 =split (/\t/,"$file1");
    #print "$array1[3]\n";
}

foreach ($array[0])
    {
        foreach ($array1[3])
{

                if($array[0] eq $array1[3])
                {
                    
                    print FILE3 "$array[0]\n";
                }
                else
                {
                    
                    print FILE4 "$array[0]\n";
                }
