The main reason why you are using sftp is for security. Why would you
want a script with a password somewhere around.

if the script is run via shell manually, use a ssh-key with a passphrase
and use ssh-agent.

if the script is run via cron, use a passphrase less ssh key, and have
a restrict on the authorized keys to specify which host and which
command can it run.
