Cron

By default, /var/spool/cron/crontabs/root is read only, use :w! in vi to save.

kill $(cat /var/run/crond.pid)
vi /var/spool/cron/crontabs/root

ESXi will overwrite cron file on boot, change /etc/rc.local.d/local.sh to update cron file

# /etc/rc.local.d/local.sh
kill $(cat /var/run/crond.pid)
echo "* * * * * <cron job>" >> /var/spool/cron/crontabs/root
