Cron jobs question

[Robert Spiteri <rspiteri01@gmail.com>]

I need to make a cron job to check if a particular directory is empty or not. The cron job is supposed to be readily available when the live system boots. How can I do that?

My intention is to change the trash icon to a full one when a file is deleted. I will be using pcmanfm.

thanks in advance.
