yum, crontab and logwatch

[Sharon Kimble]

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?

I know that I can run it as a 'service' but that means that it runs at the 
same time as logwatch and it then doesn't get recorded in logwatch, so I'm 
hoping that if I run it in advance of logwatch, then logwatch will record
it.

Sharon.
