Cron Script

with cron, it may be simpler to schedule the job to run at the beginning of every month at 00:00 hrs.

crontab entry for 1st day of month:

0 0 1 * * /sbin/shutdown -r now

0 0 * * * if [[ $(date +'%d') -eq $(cal | awk '!/^$/{ print $NF }' | tail -1) ]]; then /sbin/reboot; fi;

http:#a38395901 seems to restart 24 hours earlier than requested

so which is the right syntax i need to use

Well, this will determine if it's the last day of the month:

if ! [ "$(/bin/date -d "`/bin/date` + 1 day" +%m)" == "$(/bin/date -d "`/bin/date`" +%m)" ]; then echo "reboot, last day"; fi;

But http://#a38394375 will reboot on the first day of the month at 00:00 -> this is the 'last' day of the month, right? :)

24:00 hrs on the last day of the month is the same as 00:00 hours on the first day of the month

@ozo - that's what I mean ;)

If you run the cron job at  00:00 hours on the last day of the month, you can tell shutdown to reboot 24 hours from now.

Thanks
