Cron commands – derived from the Greek word “chrono,” which means “time” – can be useful to execute a script or command at a specified scheduled time. It is a Linux OS daemon that works in the background after it is initially loaded. Linux hosting uses this primarily for synching e-mails, system administration, and a host of other features.
Running pre-scheduled processes on your website using cron commands makes upkeep easier. For example, you may want to run processes, such as thumbnail generation or procedures for data enrichment in the background so that the user interface will not be interfered with. You can also use it to automatically create backups, schedule updates, and synchronize files.
These commands use a format script that is reliant on asterisks at the beginning of each code. Each asterisk is representative of different date “stamps,” or when exactly you want to execute a certain task. A single asterisk is minute based, two is for the hour, three is for the day of the month, etc.
