cron job misfires
I had a one time cron setup yesterday

say for eg.,
Code:
22 04 17 11 5   <job>

By mistake i gave 5 instead of 4. This job happened to run withou any problem even though it was wrong day.

I forgot to comment this cron and today again it ran.

ie., Date is wrong but Day (5) is right.

Is there any precedence theory in cron ??

Just weared.

Can somebody put some light on this ?

thx.

crontab(5)
Quote:
Note: The day of a command's execution can be specified by two fields -- day of month, and day of week. If both fields are restricted (i.e., aren't *), the command will be run when either field matches the current time.

From man crontab:
Quote:
Finally, if either the month or day of month is specified as an element or list, and the day of week is also specified as an element or list, then any day matching either the month and day of month, or the day of week, shall be matched.
Read: specifying both a date & a day of the week means the job will run on both occasions.
