[SOLVED] Run immediately then every 4 hours in cron

Issue

How do you write a cron job which immediately run, then run on every hour divisible by 4? Say I started the script at 13:25, the job fires up right away, then the next run would be at 16:00, 20:00, 00:00 and so on.

Solution

For the first immediate run, just execute the command manually. Then set your cron up like this to have it execute continuously every 4th hour

 0 */4 * * * yourCommand

This will run yourCommand every 4 hours (00:00, 04:00, 08:00......)
