multiple pattern matching

[Sunita.Pradhan]

Hi All

I have one output of one my command like :

$output = "Step 155 of 171 steps.....................................Executing.
    Step 168 of 171 steps.....................................Executing.
    Step 171 of 171 steps.....................................Executing.
    Local:  COMMIT............................................Done.

      New symdev:  2552
      New symdev:  2553
    Terminating the configuration change session..............Done." ;

I need to get those numbers like 2552 , 2553 .

I am applying following patter matching logic but it does not get me the  1st 
number (2552) .

@devs = $output =~ m/New symdev:\s*([0-9A-Fa-f]{4})/gis;
                        print $output,"\n";
                        print "Devices >>>> @devs <<<<<<<<<\n";


Could you please check what is going  wrong in  the above lines ?


Thanks
