We have several sites that use pqinsert(1) to distribute data. The trick is to run pqinsert(1) from a script that removes the file if pqinsert(1) terminates successfully. That way you don't have to worry about duplicating files. > Another option would be to give pqinsert as an -exec argument to find, but > that seems...like something I would do. :-) > > It could be that I've missed something, but it seems like most of the > documentation is (understandably) written toward receiving data, not > originating.
