It's a windows thing!
Yes, indeed. Redirection to a file in unix works like this: - open output file for truncate (>) or append (>>) - start all processes involved in the pipeline - keep data flowing through the pipe to the file till something quits. In windows/dos, it seems to go something like this: - run the first process in the pipeline, and put its output somewhere; when it finishes: - start the next process (if any) and pass it the output created by the previous process - when the last process is done, write its output to the redirection file. Maybe windows does something to create the file first (else you'd get a "file not found" error from unlink), but it's protected until the OS is done with it (which is after your process exits).
