Hello mrAibo,
You might get some joy from the output of the stat command. The file is Modified as it is created and Changed as the content is written, however this might not be safe for a polling process to be sure the file is complete.
What is the overall goal of the process you are looking to automate?
It might be safer to write a flag file when the real IO has completed, e.g. the file name might be abc123def456.output and this grows as the data is written/transferred. At the end of the writing process, just touch abc123def456.output.complete A reading process should look for files ending .complete and only then attempt to work with the real data file. Of course, there is then an extra file to tidy away and an extra IO, but the time taken should be negligible.
Does this better suit what you need, or have I missed the point?
Kind regards,
Robin
