Try this:-print
"$cmd_param_show->{'scsitrace_start_log_to_disk_true'}->{'param_val'}->{'log-to-disk'}\n";

I have following data structure :

'max-chain-size' => 16,
'max-file-size' => 0}}, 'scsitrace_dump' =>

=> 'false', 'enabled' =>
'false', 'max-chain-size' => 16,
'max-file-size' => 0}},
};
How can I access single value from this hash without using loop ?
I tried to print like :print
"%{$cmd_param_show}->{'scsitrace_start_log_to_disk_true'}->{'param_val'}\n";
It failed .Please help me to get this.
ThanksSunita
