Does anyone know an easy way to tell if a large file copy is complete?  we have many programs creating/copying files to Type 19 directories and we also have a main program scanning these directories to ftp files to Windows servers to make them available for users.  We need to make sure the main scan program does not pick up a file until the copy is complete.
We are on Linux, Universe 11.1.3.

The traditional method is to have the process that is doing the copy output a trigger file when the copy is complete. Your main scan program looks for the trigger file. When it sees the trigger file it knows the main file copy is complete.

how issue is that we have hundreds of programs that do the copy so we do not want to have to change every program if possible.

Sandy,

Can you easily change the copy routine/method?

If so, put the file in another (temp/work) directory on the same filesystem, then when the copy is completed move to the final location.

Sandy,

Did you find a solution? I'd like to know how it worked out if you don't mind.

Another simple solution would be to copy the file to a working name and then rename to the correct name after the copy has completed. For instance, copy 'fred' to '_fred'. Then rename '_fred' to 'fred' after the copy has completed. If these are done in series, the copy will be completed before the rename is done.
