How to run a cron job

Cron is a software utility in Unix-like computer operating systems, which works as a time-based job scheduler. It can automate a command to run at fixed times, dates, or intervals.

A cron job is a command or script that is typically created and run to set up software environments or automate system maintenance and administration. For example, you could set a cron job to delete temporary files every week to free up disk space.
