This is probably simple but I am not able to wrap my head around this one -

I have a subroutine that checks to see if a status is 0 yet - what I would like is loop through until the status returns 0. How would I do this?

# Code to loop sub routine checkCopyStat
?????

#sub routine
sub checkCopyStat {
   my $clTyp = shift;
   $status = 0;
   open OUT, ">/usr/local/emc/bin/temp.txt" or die "unable to open fil
+e: $! \n";

   my $name = "LUN 120 DB"; # for test purposes

   my $navicmd = `naviseccli -address $spa -user $nviusr -password $nv
+ipwd -scope global clone -listclone -Name "$name" -cloneid $copies{$c
+lTyp} -Clonestate -PercentSynced`;

   print OUT "$navicmd"; #put contents into a temporary file
   close(OUT);

   open FILE, "< /usr/local/emc/bin/temp.txt" or die "unable to open f
+ile: $! \n";

   my %hash;
   while (<FILE>) {
      my ($col1, $col2) = (split /:/, $_)[0,1];
      chomp($col1,$col2);
      if(!$col1) {next;}
      if(!$col2) {next;}
      $hash{$col1} = $col2
   }

   foreach my $key(%hash) {
      if($hash{'CloneState'} =~ /Consistent/) {
         $status = 0;
      }elsif($hash{'CloneState'} =~ /Synchronizing/) {
         $status = $hash{'PercentSynced'};
      } else {
         print "State Unknown for clone\n";
         $status = -1;
      }
   }

   close(FILE);
   unlink('/usr/local/emc/bin/temp.txt');

   return($status);
}
