Hello IB2017,

The Browser::Open module determines an OS-sppropriate value for $cmd and then executes a call to system($cmd, $url);. So if the equivalent call fails on your OS when invoked directly, it will fail similarly via a call to open_browser. For example, on my system (Windows 8.1, 64-bit, Perl 5.28.0):

21:47 >perl -wE "system('start', 'https://www.google.com/search?q=fina
+nce&source=lnms&tbm=isch');"
'source' is not recognized as an internal or external command,
operable program or batch file.
'tbm' is not recognized as an internal or external command,
operable program or batch file.

But changing the query delimiter from & to ; fixes the problem for me:

21:53 >perl -wE "system('start', 'https://www.google.com/search?q=fina
+nce;source=lnms;tbm=isch');"

— and the equivalent:

use strict;
use warnings;
use Browser::Open qw( open_browser );

my $url = 'https://www.google.com/search?q=finance;source=lnms;tbm=isc
+h';
my $ok  =  open_browser($url);

printf "\$ok = >%s<: %s\n", $ok,
        !defined($ok) ? 'no recognised command found' :
         $ok == 0     ? 'command found and executed'  :
                        'command found, error while executing';

works correctly:

21:58 >perl 1952_SoPW.pl
$ok = >0<: command found and executed

Hope that helps,
