You don't say what command, but you should check to see if it has a batch mode, and run it in with whatever args are required to make it run as such.
On some systems, you could also pipe a Y into the command before hand ( system("echo y | command").
And, finally, you can use a comibination of pipe and exec to read from/write to an external command.
IIRC, IPC::Open2 and IPC::Open3 try to simplify the last, but can still deadlock (ie, both you and the command trying waiting for the other to say something).
