- What is cron, and how do you read crontab syntax?
cron is a Linux service that runs commands on a schedule. Each crontab line has five time fields - minute, hour, day of month, month and day of week - followed by the command, so "30 2 * * 1-5 /home/ravi/backup.sh" runs the backup at 2:30 AM every Monday to Friday.
