It may work, but I disagree that it is a good solution: it will blow up when `$_->{Sub_URL}` contains shell metacharacters, and is a security hole if that variable contains any user input. See Calling External Commands More Safely. In this case I would recommend `systemx` from IPC::System::Simple, or at the very least the multi-argument system (as shown in other replies) with error checking (nobody showed this, but for an example see the first link). sigh	[reply] [d/l] [select]
