this will open your personal crontab (cron configuration file), the first line in that file explains it all (don’t you think)! In every line you can define one command to run, and the format is quite simple when you get the hang of it. So the structure is:<\/p>\n minute hour day-of-month month day-of-week command You can also use intervals, they are defined like this: *\/20 this example means every 20th and if in the minutes column this will be equivalent to 0,20,40 or every 15 minutes<\/p>\n Note that the day-of-week goes from 0-7 where 0=7 is sunday.<\/p>\n","protected":false},"excerpt":{"rendered":" Put a shell script in one of these folders: \/etc\/cron.daily, \/etc\/cron.hourly, \/etc\/cron.monthly or \/etc\/cron.weekly.
