The format of the job is like this. I'm gonna use some varibles, you should remember
those from algebra, for those of you that don't it is a letter that represents another
value (usually a number).
a b c d e f
where...
a = The minute after the hour that you want it done
b = The hour you want it done (Military Time)
c = Day of the Month
d = Month of the Year
e = Day of the week
f = 'command'
- Code: Select all
5 0 * * * /usr/local/bin/email
Like the above example, /usr/local/bin/email, will run every night at 12:05 AM.
The * means to run every instance of the value in the field. Like a asterisk in the day field means to run everyday
