Fedora 20: Updating via the command line

  Fedora, unlike Ubuntu with apt-get, uses yum to update it’s software. Run the following as root (either by logging in as root or using su in front of the command):  
yum update
  You will see a list of the updated packages and a confirmation at the end. On our test system it looks like this:  
Transaction Summary ============================================ Install   3 Packages (+  6 Dependent packages) Upgrade  97 Packages (+157 Dependent packages) Total size: 332 M Total download size: 275 M Is this ok [y/d/N]:
  If you are happy with the listed upgrades and/or new installations hit ‘y’ to update!
