The "cksum" is safer than the "sum" command in this context. If you have Linux rather than unix there are more different commands.

The best simple design option is to send files under a temporary filename and rename them after successful transmission.
Another technique is to send a suitable "finished" dummy file after a successful main transmission.

A belt-and-braces approach is to send a uniquely numbered batch header file containing filenames and checksums and after the transmission of files prefixed with names containing the unique batch number send a matching trailer file containing the same information. After checking that the header and trailer exist and agree, the process should then check the checksums of all files in the batch before allowing processing of the data.
It is actually easier to implement than it is to describe.
Btw. This is better than BACS.

If you cannot modify the process then testing whether the file is open with the "fuser" command is one option and others have suggested checking for file growth by various methods.
Checking with "fuser" or testing for file growth is no guard against failed transmissions.

ipsec_config_batch

ipsec_config_batch(1M)													    ipsec_config_batch(1M)

NAME

       ipsec_config_batch - allow for processing of IPsec config operations in a single batch file

SYNOPSIS

       batch_file_name profile_file]

DESCRIPTION

       The command allows you to specify multiple and operations in a single batch file for processing.  HP-UX IPSec processes the operations in a
       batch file as a group.  This mode is useful if you are adding or deleting configuration records that may affect other records.

       If one operation is invalid, all operations in the batch file fail.  The utility first verifies each operation in the batch file for syntax
       errors  and  collisions	(object  names and priority values) with existing entries in the configuration database.  If all operations in the
       batch file are valid, the HP-UX IPSec infrastructure updates the configuration database with all operations at the  same  time.	 If  HP-UX
       IPSec is active and running, the HP-UX IPSec infrastructure also updates the runtime policy database.

   Options and Operands
       The batch operation recognizes the following options and operands:

	      batch_file_name
		   The name of the batch file containing and operations.

		   A batch file cannot contain operations that operate on the following objects:

				 For example, the
		   operation is illegal in a batch file.

		   In addition, a batch file cannot contain the following commands:

		   o  does not allow recursive batch files) or commands.

		   o

		   o

		   Lines starting with a pound sign are interpreted as comments.  Comment lines within an operation are not allowed.

		   Maximum length: 1023 characters.

		   Default: None.

	      The  utility  verifies the and operations, but does not add or delete entries in the configuration database.  This option applies to
		   all operations in the batch file.  Individual operations in the batch file cannot specify the option.

	      Specifies the name of the profile file containing default argument
		   values for this policy.  The argument values are evaluated once, when the policy is added to the configuration database.   Val-
		   ues used from the profile file become part of the configuration record for the policy.

		   This  argument applies to all operations in the batch file.	Individual operations in the batch file cannot specify the profile
		   argument.

		   Maximum length: 1023 characters.

		   Default:

EXAMPLES

       The file contains the following entries:

AUTHOR

       was developed by HP.

FILES

       configuration database.

       default			profile file.
