Crontab

Definitions

1. The configuration file and command for managing cron jobs on Unix systems. The format uses five fields (minute, hour, day-of-month, month, day-of-week) followed by the command to execute. Despite its cryptic syntax, crontab remains the most widely used job scheduler on Linux servers.

   In plain English: The configuration that tells a Linux server to automatically run tasks on a schedule.

   Example: "Add 0 2 * * * /usr/local/bin/backup.sh to your crontab to run backups at 2am every day."
