The given statement that is Cron only allows the user to create one time tasks is true.
On Unix-like operating systems, a job scheduler is the command-line tool cron. Cron is a tool used by those who set up and maintain software systems to plan tasks, sometimes referred to as cron jobs, to run on a regular basis at predetermined times, dates, or intervals.
The term Cron, a clock daemon, comes from the Greek word Chronos, which means time. It allows users to programmatically execute instructions, scripts (a collection of commands), or programmes at predetermined intervals.
A persistent process that runs instructions at predetermined times and dates is the cron daemon. This can be used to schedule tasks that are either one-time occurrences or ongoing duties. Use the at or batch command with cron to schedule one-time tasks.
