Re: how to tell if a file is still being modified (use the filename as a communications channel)
in thread how to tell if a file is still being modified
This is the method we use in batch processing at one of the largest banks in the US. Another method is to poll the size of the file every so many seconds. After the file doesn't grow for N polls (usually 2), we can assume the file is done. -s isn't that expensive, especially in the batch world.
We are the carpenters and bricklayers of the Information Age.
The idea is a little like C++ templates, except not quite so brain-meltingly complicated. -- TheDamian, Exegesis 6
