General :: Can't Seem To Figure Out \ Script A Simple Closed Loop?

I think I can do it by brute force with a crontab entry for each of the 15 days at a time, but I'm not even sure I know how to do that.I'm trying to automate a process I do manually every day. That is, I execute the same command every day for 15 days running, manually changing the filename of the file by 1 each time, i.e. file.1.dmp, file.2.dmpThen after I reach the end of 15 days, I start again changing the filename being written back to the name of the first file I created 15 days ago. This overwrites the 15 files one a day for 15 days. That is, after I create the file.15.dmp, I (manually) change the name of the file being created back to file.1.dmp again.

I realize that this may not be descriptive enough to help me with getting an answer. I don't know how else to explain it. I'd be more than glad to fill in any details I've missed.I've thought about using a for loop, but it's been so long since I've had to do any programming I hesitate to go down that path. I've though about using the current date variable to change the filename, but how do I reset the script to start again after 15 days?The point of my exercise is to have a rolling backup/dump file for 15 days that I can restore from if needed.
