Perl variables in exec or system

I am new in Perl.

I am working in simple script and the varibles are working well outside the exec or system command.
but they don't work as parameters to exec or system command.

The script is attached.
please help.

I think it's the way you are using quotes. Try this:
exec "ovownodeutil -add_exnode -group_path $group -caption $line -other $line -check_before_managed_nodes";

Dear Mark,

Thank you very much for your reply.

The code worked well and the variables are passed.

But as you made sense I add nodes to an application which are listed in a file.

After making the modificatio you have advised, the script added only the first node of the list.
Please advise.

Hi Ahmed,

The problem is because you are using exec which does not return after executing - see exec - . Try using system instead of exec.

Thank Mark.
When I replaced the exec with system, the script didn't sense some options of the executed command.

I got the following error:
ERROR: (NDUT9005) Option -caption missing.

although the -caption option exists.
Why the system command sense that it is missing?

Please paste the actual perl code you are running so I can have a look.

print "Prepare the \"nodes.txt\" file in drive C then press enter:";
$enter = <>;
print "\n";
if ($enter == "\r")
print "Enter the parent node group name: ";
$group = <>;
print "\n";
$FILE = "nodes.txt";
open(FILE,"< C:/nodes.txt");
system "ovownodeutil -add_exnode -group_path $group -caption $line -other $line -check_before_managed_nodes";
print "$line";
