crontab for 1st wed. each month.

[Guest_imported]

is it possible to run a cron job for the 1st wednesday of each month or do i need a script? if i need a script, what would it be?

FYI:if it matters, this is for AIX.

thanks.

The following will run 'do_something' at 4am on Wednesdays that are the 1st-7th of every month (which is the same as 1st Wed of every month).

0 4 1-7 * 3 do_something

i thought of that but the man pages say:

" * If either the month of the year or day of the month fields is specified as an element or list and the day of the week field is also specified as an element or list, then any day matching either the day of the week field, or month of the year and day of the month fields are matched."

so wouldn't that run on every day of the 1st week of the month and every wednesday?

You could put a condition at the start of the script that says something like
if test `date "+%A"` = "Wednesday"
then
echo "It's Wednesday"
fi SOL
"If I'm talking c**p, I'm probably p****d"

You could expand on that :-

If `date "+%A"` = "Wednesday"
then
if `date &quot;+%d&quot;` < 8
then
echo &quot;Its the first Wednesday&quot;
fi
fi

That seems simple enough.

Thanks everybody!
