Top Forums UNIX for Dummies Questions & Answers Run a cronjob only when a file is modified? Post 302598906 by ad23 on Wednesday 15th of February 2012 04:52:44 PM
Old 02-15-2012
Thanks a bunch! I understand now.

Also, I want to add a check-point to this: to avoid updating the database while the input-text-file is being updated or if the file is corrupt (or does not exit). Is it advisable to check by file size, since the updated file will be larger than the old file? If yes, how can I accomplish this?

Thanks!
