How to use SFTP BatchMode inside EXPECT[Shell Script]

Question

I have set of series SFTP commands which needs to run inside expect.

But when i run the below script due to some reasons am not getting any output. Please correct me if am wrong any where inside the script.

expect << EOF spawn sftp -oPort=23 -oBatchMode=no -b cmds.txt [email protected] sleep 3 expect "[email protected]'s password:" send "hello123\r" EOF 

But when i run below command in CLI interface it works super good:

# spawn sftp -oPort=23 -oBatchMode=no -b cmds.txt [email protected] 

For Security Reasons, I cant use SCP, SSHPASS, KeyChain Etc.,

Once you have told expect to send the password, it has nothing to do so it stops and kills the sftp. Add a wait for end-of-file from the spawned command:

expect eof 

You can get more debug from expect by starting it with expect -d.
