SCP file transfer command on solaris

I need to transfer multiple files using SCP between two solaris machines. Can somebody explain how to achieve that ?

% scp /home/parthum1/* user2@machine:/home/parthum2

/home/parthum1/ - Source Directory
user2 - user name of the destination machine
machine - machine name or ip address of the machine
/home/parthum2 - destination directory

Ok.... since we have the basic command to copy the files.

Do any body know how to get around the password entry phase for the user on the remote machine.

I checked this article on the net which helps to "pass on passwords with SCP".

Any alternate ways available to "pass on passwords" instead of generating public/private keys ?

Thanks in advance.

what would be the point of using scp then?

Why not just rcp them?
