使用密钥和密码自动进行SFTP登录

Question

Recently SFTP hosted servers are enabled with two factor authentication. For details please refer the link here.

Now, we have requirement to automate this setup using command line. I found that as two different options for doing this:

 sshpass -p password sftp -oBatchMode=no -oStrictHostKeyChecking=no username@server1

 sftp -oIdentityFile=/path/to/private/key/file -oBatchMode=no -oStrictHostKeyChecking=no username@server1

But now I need to combine these two into single command and use it in my script for automating this sftp flow.

So, at first I need to send the private key file in the command line and then send the password in the same command line. I tried few options but it didn't work.

Answer 1

How hard can it be to put both lines together:

sshpass -p password sftp -oBatchMode=no -oStrictHostKeyChecking=no \
  -oIdentityFile=/path/to/private/key/file username@server1

ssh itself will take care of both authentication methods.
