sftp batch mode and password authentication

[ponraj]

Hi all,

I used to execute ftp in batch mode to dowload files. In my case, password 
authentication is the only way to get remote access. Could anyone tell me 
how can i accomplish the same task using sftp under batchmode as what i have 
done with ftp ? Meanwhile, how can i specify the password securely ? Is 
there anyother alternatives ?
