Verify file was sftp'd via bash script
Hello Experts,

I have a script that that transfers a file (via sftp) and it works fine but we ran into a snag where the target server asked for the ssh key and the script didn't know what to do. I want to add some logic to this script that at least sends an email that it didn't complete as expected or didn't transfer the file.
Code:
#!/usr/local/bin/expect --
spawn sftp support@target_server.com
expect "password: "
send "support\r"
expect "sftp>"
send "put /home/root/filename.txt . \r"
expect "sftp> "
send "quit\r"

I'm testing it now on our network and get the following results:

./test_ftp_script
spawn sftp support@target_server.com
Connecting to target_server.com...
The authenticity of host 'target_server.com (10.101.21.34)' can't be established.
RSA key fingerprint is ce:5d:35:c6:57:8d:f5:d5:45:ac:b4:a5:3e:22:e6:f1.
Are you sure you want to continue connecting (yes/no)? support
Please type 'yes' or 'no': /home/root/filename.txt .
Please type 'yes' or 'no': [server:/home/root/]#

Note: I have altered the names on the script via cutting and pasting, so there may be an extra period, etc.. here or there

Thanks!

sftp-server

SFTP-SERVER(8)						    BSD System Manager's Manual 					    SFTP-SERVER(8)

NAME

     sftp-server -- SFTP server subsystem

SYNOPSIS

     sftp-server [-ehR] [-f log_facility] [-l log_level] [-u umask]

DESCRIPTION

     sftp-server is a program that speaks the server side of SFTP protocol to stdout and expects client requests from stdin.  sftp-server is not
     intended to be called directly, but from sshd(8) using the Subsystem option.

     Command-line flags to sftp-server should be specified in the Subsystem declaration.  See sshd_config(5) for more information.

     Valid options are:

     -e      Causes sftp-server to print logging information to stderr instead of syslog for debugging.

     -f log_facility
	     Specifies the facility code that is used when logging messages from sftp-server.  The possible values are: DAEMON, USER, AUTH,
	     LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7.  The default is AUTH.

     -h      Displays sftp-server usage information.

     -l log_level
	     Specifies which messages will be logged by sftp-server.  The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1,
	     DEBUG2, and DEBUG3.  INFO and VERBOSE log transactions that sftp-server performs on behalf of the client.	DEBUG and DEBUG1 are
	     equivalent.  DEBUG2 and DEBUG3 each specify higher levels of debugging output.  The default is ERROR.

     -R      Places this instance of sftp-server into a read-only mode.  Attempts to open files for writing, as well as other operations that
	     change the state of the filesystem, will be denied.

     -u umask
	     Sets an explicit umask(2) to be applied to newly-created files and directories, instead of the user's default mask.

     For logging to work, sftp-server must be able to access /dev/log.	Use of sftp-server in a chroot configuration therefore requires that
     syslogd(8) establish a logging socket inside the chroot directory.

HISTORY

     sftp-server first appeared in OpenBSD 2.8.
