I'm trying to create a script that will monitor all non-admin user home directories under /HOME for growth of over 100MB in a 20 min period, and send an email to root if this occurs. The email needs to contain a list of users that were found in violation of this.

I'm rather new to Unix, and I can easily write pseudo code for this, but translating it into code is proving to be a difficulty. I'm thinking it would go something like this:

For (all folders under /HOME) {
   - store folder size in a variable
   - store current timestamp in a variable
   - when time += 20 min, get new folder size and compare
   if  (new size - old size > 100+)
       - send email notification to root with offending username
   else (exit)
}

Any help would be greatly appreciated! I'm really struggling with this.

    Even if your pseudo-code was correct, this probably wouldn't protect against accidental or intentional denial of resources. Look into per user disk quotas and let the operating system prevent disk hogging. – msw Jul 30 '14 at 19:49
