I have a pretty demanding requirement for an SFTP script I have been trying to put together.
I have nearly 100 files (all with the names staring with T_PROD) generated in my local server daily. I need to transfer each of these files to a remote server via SFTP (that's a client demand, can't use SSH or others). Since these files are pretty big (approx 10 MB each), we need to have a check on succesful transfer of each of the files. In case a file is not transferred properly, we will be trying to re-send the file, at max 3 times.
Since it's SFTP, we're not allowed to execute shell commands in the remote server. I tried creating the md5sum hash values, but stuck thereafter. How do we identify the exact files those failed the sanity check, and try re-sending them?
A barebone structure of the script is as below
I'm running this script in Linux kernel 2.6.39
Do let me know if any further information is required.

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.
