We have a ksh which runs once every 15 minutes. Based on a certain condition (for invalid data) we are spooling a file and if the file is of length greater than 0 bytes, then we are mailing this file to a group of users. Upon receiving the file, users correct the data so that on its next run the same data is not selected and the file spooled becomes 0 bytes and hence is not mailed across.
But, it mostly happens that users take more than 15 minutes to correct the data and hence this job creates the same file and mails it to the uses again.

What I am looking for, is there a counter logic which I can set and which will allow me to send the file only once of it is greater than 0 bytes.

Best would be - once the file is created with more than 0 bytes for the first time, it will be sent only once(i.e for the first time) and after that, say, for the next 2 hours( which implies 7 more cycles), this file, even if gets created will never be mailed at all.

Thanks,
