ped is a process execution daemon, comparable to cron in its basic functionality. It monitors a given directory. If a user or an application drops a file into this directory, ped parses the content and executes a given command. The syntax of these files describes the functionality: "[from (unixtimestamp)] [until (unixtimestamp)] [asuser (username)] start|restart|loop (command) [(parameter)]". ped was primary written to schedule time-consuming tasks initiated by a Web application.
