@Paul: process_file() would delete the file after processing...it would process the file, write the output to a different directory, and then delete the processed file. But, the way we read files in a directory through readdir, how do we write output of each of the processed files to a different directory. @Rob: After processing each of the files, if we are removing them, then why do we need last access time here. It is guaranteed that any touched file in the child directory is present in the parent directory. We just need to pick that up, process it and remove it from both parent and child directory after processing. But how do we write multiple output files in a different directory. @Shawn: Hey Shawn, the input file will first come into the parent directory, but it will not be a fully written file as soon as it comes. It will still be processed and written by some other program. Only when it is fully written, it is touched into the child directory. So, if we pick up only those files which are touched into child and then remove them after processing, then there should not be an issue with files getting repeated. Thanks, Mihir
