Hello to all,
I have recently started with perl. Sorry for my English.
I have some Dupplicate in Path variable.(by the installation of some apps that you can see two identical addresse written in Path).
my goal is that I just change path and these changes may remain when I reboot system. I have a script with perl written that you can delete dupplicate but in the end I see it again. This means my script has no effect on Path enviroment variable.
how can I change that path variable so stay with the reboot the changes?
thank you for your help in advance
here is my code:

........for test........ 
#<<forTest
$ENV{'PATH'}='/bin;/usr;/bin;/usr/local/bin:/home/fred/bin';
#<< or 
  $t = $ENV{'PATH'};
@array=split(/;/,$t);
# zeigt jede node vom array
 foreach (@array){
    
#  print "$_\n";
 }

  $flag = 0;  
 
  for ($i=0;$i<@array.length;$i++)
 {  
    
     for ($j=$i+1;$j<@array.length;$j++)
   { 
     if (@array[$i] eq @array[$j]) 
   {
   
      print "[", @array[$i], "]";
      print "  is equal to " ;
   
     print "[", @array[$j], "]";
     print "  index vom array : ";
       print $i  ;
       print ",";
     print  $j , "\n"  ;
   
     @array[$i] = '';
     
 $flag = 1 ;
     
    } 
  
   }
 
  
 }

  
 if ($flag == 0)
 {print "no Duplicate :D \n";}
 
 foreach (@array){
    
# print "$_\n";
   
 }
  print " old Path: \n";

 
 print $ENV{'PATH'};
 print " \n";
   print " new Path: \n";
   $TEMP = '';
   for ($i=0;$i<@array.length;$i++)
 {
     if (@array[$i] eq '')
     {$TEMP = $TEMP . @array[$i] ;}
    else {$TEMP = $TEMP . @array[$i] . ';';}

   
 }
  $ENV{'PATH'} =  $TEMP ;


    print $ENV{'PATH'};
  print " \n";
