Just a quick post to show how to monitor usage of /tmp on a Linux system. Setup a cron job as follows…

* * * * * df -h | grep "/tmp" >> /tmp/tmp.log

This job will run every one minute logging details of /tmp usage to a file called tmp.log. To report on this later you can run the following command to get a unique ordered list.

cat /tmp/tmp.log | sort | uniq
