Running a cron job on Linux every six hours

by

You forgot a *, and you’ve too many fields. It’s the hour you need to care about

0 */6 * * * /path/to/mycommand

This means every sixth hour starting from 0, i.e. at hour 0, 6, 12 and 18 which you could write as

0 0,6,12,18 * * * /path/to/mycommand
