Yep. Instead of checking the $? or $! I played a trick.This code sinppet inside a function. 
 my $status = `gzip -cd filename 2>&1`;
   print "The status is:$status\n";
   if (!($status eq ''))
   {
            print " ERROR : $file is corrupt. \n";
      return 0;
   }

It works!!! But do you think this is the right way to tackle?

But problem is when I am trying to close a pipe handle. I did somethig like that:

use IO::Pipe;
my @command =qw(gzip -cd filename);
my $fh = new IO::Pipe;
   $fh->reader(@command)|| warn "ERROR : Can't read : $!";
    while(<$fh>)
   {
    #doing some long job here;such as
    $variable = readline $fh;
    .
    .
    .
   }

 undef $fh;#close $fh

 if ($? != 0)
        {
         print "problem in undef or closing:$? with status:$!";
        }

I am getting the last print message as error as:problem in undef or closing:-1 with status:no child process". My question is that is it required to check the $? or $! here? If we ignore it will system dump core?
