fs-check - A Perl program/daemon for checking for full or filling filesystems

fs-check checks filesystem sizes to see if they are getting too full. It uses a configuration file that specifies the filesystems to check, email contacts, trigger thresholds (percentage or amount used/unused), and a report program to run.

Also included in the package is such a sample report program, fs-report. It shows things like the largest files, the newest files, and core files. It can be run from cron or as a daemon.

NOTE: If you want to avoid building fs-check from sources you can install MacPorts on your Mac and issue the following command from the command-line to build fs-check on your system: sudo port install fs-check.
