Answer 1

try using this

/usr/bin/expect <<EOF
spawn sftp -oStrictHostKeyChecking=no -oCheckHostIP=no mwctrl@sacsun11 \
"cd /usr/ftadapters/logs/adapters/rivaadp \
lcd /export/home/eisape \
put *.txt \"
expect "*?assword:*"
send  "m33tzn3"
send  "\r"
set timeout -1
send  "\r"
expect EOF

Setting up ssh keys is relatively simple. Takes <1 min following the instructions in the link posted above by fxzuz.

But generally passing passwords as parameters / storing in config files is considered a security risk.

However, if you still want to go ahead, here is a link -- http://nixcraft.com/shell-scripting/4489-ssh-passing-unix-login-passwords-through-shell-scripts.html

Actually you need add ssh keys to remote machine. Check article below:
