Frequently asked questions
What does 0 10 * * 6 mean in cron?

How do I run a cron job every Saturday in Linux?
Run crontab -e, add the line 0 10 * * 6 /path/to/command, then save and exit. Use absolute paths, redirect output to a log file, and confirm it runs with grep CRON /var/log/syslog.
When will 0 10 * * 6 run next?
It depends on the current time and the time zone of the machine running cron. The calculator on this page shows the next 5 run times in your local time zone; on a server, cron uses the system time zone, which is often UTC.
