Permission denied to use sftp -b batch file

Question

I can log in to my remote using ssh/sftp (without the -b option)

sftp [email protected]

But when I try

sftp -b commands.tmp [email protected]

I get

Permission denied (publickey,password).
Couldn't read packet: Connection reset by peer

Commands.tmp looks like this

ls
exit

Anything I am missing here ?

I used shhpass to write the password no interactive and I needed to add -oBatchMode=no

sshpass -p PASSWORD sftp -v -oBatchMode=no -b FILE USER@SERVER

If you are authentication with a password or an encrypted private key, you cannot use the -b with plain sftp. The sftp man says:

Since it lacks user interaction it should be used in conjunction with non-interactive authentication

You can for example use a passphrase-less private key together with the -b.

If you want to use password authentication, you need to use workarounds like sshpass. See:

This worked for me

sshpass -p 'PASSWORDSTRING' sftp -v -oBatchMode=no -b deploy/production username@ipaddress

production file

put -rp /from-directory /to-directory

thank you that worked for me; however for some reason it is important that the "-oBatchMode=no" is before the "-b" option. – Tilman Hausherr Jan 05 '22 at 08:57
