I need to transfer the log file to the remote host using sftp from the Linux host. I have been provided credentials for this same from my operations group. However, since I don't have control over the other host, I cannot generate and share the RSA keys with some other host.

Is there any way to run an sftp command (with a username/password provided) from inside a Bash script through the cron job?

You have some options other than using the public key authentication:

  1. Use keychain
  2. Use the sshpass (less secured but probably that meets your requirement)
  3. Use except (least secured and more coding needed)

If you decide to give sshpass the chance here is the working script snippet to do so:

export SSHPASS=your-password-here

sshpass -e sftp -oBatchMode=no -b - [email protected] << !

   cd incoming

   put your-log-file.log

   bye

!
