Hi.
Unless there is a prior agreement between the creating process and the rest of the universe, I don't think there is any method to guarantee that a file is "complete".
I would attempt to address this by having the creating process set some completion flag, create an additional "unlocked-now" file, etc. -- similar to perhaps to what robotronic suggested. You might investigate ownership of the files, placing the files in a holding area until the next one begins to be created and then moving the assumed-to-be-complete file to the transfer directory, writing a wrapper script around the creating process to create the complete signal, and methods along that line.
I'll be interested in additional comments ... cheers, drl

wait(1) General Commands Manual wait(1)
NAME
wait - await process completion
SYNOPSIS
[pid]
DESCRIPTION
If no argument is specified, waits until all processes (started with of the current shell have completed, and reports on abnormal termina-
tions. If a numeric argument pid is given and is the process ID of a background process, waits until that process has completed. Other-
wise, if pid is not a background process, exits without waiting for any processes to complete.
Because the system call must be executed in the parent process, the shell itself executes without creating a new process (see wait(2)).
Command-Line Arguments
supports the following command line arguments:
The unsigned decimal integer process
ID of a command, whose termination is to wait for.
WARNINGS
Some processes in a 2-or-more-stage pipeline may not be children of the shell, and thus cannot be waited for.
SEE ALSO
csh(1), ksh(1), sh-posix(1), sh(1), wait(2).
