cron capabilities

Gerry Tully — Wed, 16 Aug 2000 16:58:13 GMT

Does anyone know of a way to have a system reboot at a certain time on say the third Friday of every month? The problem I am running into is that these fall on different dates during the months. Thanks.

You can run cron as root or better at.
Also, SAM->Routine Tasks->Sytem Shutdown let you to enable a shoutdown a while ago.

Can do last day of month. Not aware of capabilities to do this unless you script something and use some arrays.

That's what I thought I would have to do but I was hoping someone knew a better way.

Write a script and cron it to run on every Friday.

At first thought, if the date is then between the 15th and 21st inclusive then it's the 3rd in the month.

Sorry Gerry,

I meant to finish...

if todays date obtained from 'date' is between the 15th and 21st inc then do your reboot:-

shutdown -r -y 0

otherwise just exit.

Try this and remark for other weeks.

30 5 * * 6 /sbin/shutdown -r 0

in your cron you could place a line:
00 04 * * 5 /your_script

And in your script, test the value of the date, I suppose a 3rd friday in the month should be between the 17th and 23rd day of the month (check it out!)
like:
if [ $(date '+%d') -lt 23 ] and [ $(date '+%d' -gt 17 ]
then

fi

For December of this year, the 3rd Friday is the 15th

And I made a mistake in the syntax, lest say:

if [ $(date '+%d') -lt 23 -a $(date '+%d') -gt 15 ]
then...

as john palmer has correctly pointed out, the 3rd Friday occurs on the 15th thru the 21st incusive. This equates to gt 14 and lt 22.

I wrote a hack script that seems to work...
it uses "cal" and cut -c16-17

thought there might be a way to do this via "at"
but guess not.
