Upgrading a package

- [Instructor] Once software's installed,…we're not necessarily finished with managing it.…New features and especially security updates…are often made available, and unless you have…very specific reasons for staying with an older version…of a package, it's a good idea…to upgrade to take advantage of them.…You can see what updates are available for your system with…yum check-up-update,…and if you want to upgrade all of the installed packages…to whatever the most current version provided in the repo is…you can just use yum update by itself.…That can take a while, so especially if you're using…a remote connection, it's a good idea to run that…in a screen or tmux session in case you get disconnected.…

I'll write sudo yum update.…I've never run yum update on this system before,…so there's a lot for yum to update.…If you're short on time, this could take 10 minutes…or more depending on how much you have to update…and how fast your network connection is.…You may want to skip updating this…many things until a later time.…
