Thanks, I found the MLM from Google so I didn't know about
http://marc.theaimsgroup.com :o)

I found a post which gives me exactly what I need, although for my own
sanity can you tell me how GnuPG knows that $passphrase is the
passphrase and $msg is the message in the stdin?

---------------------------
$command="echo '$passphrase\n$msg' | gpg --clearsign --passphrase-fd 0"
---------------------------


Thanks,

Rob
