[1]# yum check-update [2]# yum -y update [1] lists updated packages that would apply to your system and then [2] would install them. > Is there an equivalent of portage in centOS? (The portage site lists all > available packages for Gentoo by 'category'). yum group-list perhaps? Read up on RPM and Yum. RPM is the base package management for RH-like systems and Yum sort of a pull/delivery mechanism that resolves dependencies. http://www.rpm.org/max-rpm/ should have more than you need to know about RPMs. http://www.centos.org/modules/smartfaq/faq.php?faqid=8 and http://linux.duke.edu/projects/yum/ explains more about Yum. Will.
