Hi Sharon: > > I'm trying to write a crontab entry to run yum update at 0100 and this is as > far as I've got '0 1 * * * /usr/bin/yum update' but I'm unsure if this will > work. Can anyone reassure me please, or if not, what is the correct syntax? > This looks like you are editing root's personal crontab using crontab -e. Your entry is on track, but the following: 0 1 * * * /usr/bin/yum -y update is better; without the -y, yum will wait for root to accept the updates to be installed, but this won't happen via cron. -y assumes a yes answer to the confirmation prompt, so the updates will be installed. If you are running this in /etc/crontab, use the following: 0 1 * * * root /usr/bin/yum -y update When I run it as a service, I seem to get logwatch updates only if it fails, but I DO get notices via logwatch. You can edit the wordiness by editing /etc/cron.daily/yum.cron. If you make your own cron entry as you have asked, you need to add the appropriate options on the command line (-e and -d come to mind as the right options). Erik
