The official and recommended way of solving this issue is to perform 
public key authentication with the ssh server. You are right that the 
--password-file option does not work when running rsync over ssh. Public 
key authentication solves your problem, and does not significantly 
reduce the security of your system.

There is another option, but only go that route if you have tried 
setting up public key authentication and failed for a reason over which 
you have no control. If your server supports public key authentication, 
do not continue to the next option. Only consider it if the 
administrator for the server to which you want to connect has disabled 
public key authentication and cannot be persuaded to change her mind.

There is a tool called "sshpass". It is available at Read about it at
