I have made the sftp password less using the ssh -t key_gen option and the prompt for password does not appear anymore but when I write the commands to be executed on the sftp session like the following in the shell script and execute it they are not executed instead i just get the prompt of sftp
#!/bin/sh
username=$1
ipaddr=$2
external_path=$3
extension=$4
sftp $username@$ipaddr
cd $external_path
get *.$extension
exit
Result
sftp>
and nothing else
Could you please tell how this can be achieved, also the expect utility is there on my machine but the sftp does not support the -b option
Thanks, Priyanka
