Need a notifying system for unmodified files

[Naughtyus]

Hi all,
I've just set up Gentoo with DRBD and samba to be the main file share for my company, and am quite pleased with the results. My next server problem has to do with archiving of data. I'd like to set up an automatic archiving system, or at least a notification system, but I'm not sure how to go about doing it.

Essentially I'd like something that will send me an email when files at a certain level (ie. /mnt/samba/A, /mnt/samba/B, ...) are left unmodified for somewhere around three weeks. Does anyone know of any good ways of doing this?

Using find with the appropriate arguments gives you a list of files you might be looking for. You could write the result to a file and send it as an attachment to yourself. Create a cronjob and your done.

Perfect! Don't know how I missed that obvious idea.

Is there a more efficient way of doing this than running a 'find * > all.txt', and taking the diff of that and 'find /mnt/dirs -mtime +21 > output.txt'?

Essentially I want to end up with a text file with a list of all the main directories where no files contained within have been modified within the last 21 days.

Unfortunately not - I think the -d switch only looks at the directory itself.

What I have is a file share like so:
/mnt/data/project1/..
/mnt/data/project2/..
/mnt/data/projectx/..
/mnt/data/project999/..

Essentially what I want is to have a list of the 'projectx' directories if and only if one or more files contained within it have not been modified in the last 21 days. The idea here is that if a file has been modified/created in the last 21 days, then a project is active, and there is someone who will be looking at it on a regular basis, so the normal backup schedule will catch this. If however there has been no activity in a project for 21 days, then it is possible that a project could be deleted without anyone noticing - after ~30 days, the backup media will be overwritten, and the project will disappear. To ensure that this doesn't happen, I want to 'archive' any/all of these inactive project directories - but I need some method of figuring out which projects are actually inactive (since I can't trust my users to tell me)

I think I've found a solution now. I doubt there is no more elegant solution but it should work if I've correctly understood what you want. You need a tiny script for that: (I've called it check.sh)
