in thread Have a perl script launch another script or program, then write to that script's STDIN

The situation is this: I have several daemons that need to access some encrypted data to perform different operations on it. For security purposes, I want to enter the decryption password when I start the daemons, using:

system('stty','-echo'); my $input=<STDIN>; system('stty','echo'); chomp($input);

To make life easier for myself, I want to have one script that will start all the daemons so that I only have to enter the password once, after which this script will launch all the other daemons and provide them with the password. However, I don't know how to have the script give the daemons the password.

Does my question make more sense now?
