Maybe someone can correct me if I'm wrong, but I'm pretty sure you can't access the file system through an iRule.
As a possible way around that, you could set your cron job up to run a
tmsh
command to update a data group
with your unique string. Then your iRule could read the string from the data group (I don't believe you can update a data group record within an iRule though).
Hope this helps.
