Ahmed,

I think this is because $group includes a linefeed because you are entering it from the command line when you reply to "Enter the parent node group name: ". When the system command interprets the arguments you are giving it then it sees:
Code:
system "ovownodeutil -add_exnode -group_path $group<linefeed>
-caption $line -other $line -check_before_managed_nodes";

so the -caption is seperated from the call to ovownodeutil and you get a message from ovownodeutil saying it is missing -caption.

I think the way around this is to chop off the linefeed after you read $group so you need to add command chomp $group like this:
Code:
print "Enter the parent node group name: ";
$group = <>;
chomp $group;

Code:
##your code above
$group = <>;
chomp $group;#<-- chomp user input to remove the newline
##your code below
