Does anyone know what's the difference between the below command in CentOS Linux ?:
dnf update yum update
Which one is better to use with Cron as automated OS update?
Thanks in advance.

yum was replaced with
dnf in CentOS 8. The command
yum still exists because people will still remember it for years to come. The only thing it does is to call
[root@localhost ~]# ls -l /usr/bin/yum lrwxrwxrwx. 1 root root 5 Jul 21 18:46 /usr/bin/yum -> dnf-3 [root@localhost ~]# file /usr/bin/yum /usr/bin/yum: symbolic link to dnf-3
