cron

[Ramnath S]

Hi,

I need to enter one entry in cron where it will reboot the server on First and Third thursday of every month. Can anyone suggest on this.

Thanks in advance.

You have to write a script to check 1st and 3rd thursday for every month since cron is not user friendly.

For Ex:

15 4 * * 4 /usr/sbin/shutdown -ry 0 >/dev/null 2>&1

Which will reboot server Every Thursday at 4:15am

Best way is use Clay's script to do your cronjob. See the link for more details.

Hi,

Schedule this to run every Thursday:

#!/usr/bin/sh
DATE=$(date +u"%d")
TH1=$(cal | awk '{if ($5 != "Th" && $5 != "") print $5}' | head -1)
TH3=$(cal | awk '{if ($5 != "Th" && $5 != "") print $5}' | head -3 | tail -1)
if [ "${DATE}x" = "${TH1}x" -o "${DATE}x" = "${TH3}x" ]
then
shutdown -r -y now
fi
exit

A sample crontab entry (which runs every Thursday at 1:00am):
0 1 * * 4 reboot-1st-3rd-th.sh
