yum updateYour Linux system contains hundreds, if not thousands, of software packages, and upgrades come out constantly for one package or another. It would be a full-time job for you to manually keep track of every new version of your software and install updates, but yum makes the process easy. A simple yum update command tells yum to check for any upgrades to the software it's tracking. If new packages are available, yum shows you what's available and asks your permission to proceed with an install. # yum update Setting up Update Process Setting up repositories update 100% |====================| 951 B 00:00 base 100% |====================| 1.1 kB 00:00 Resolving Dependencies --> Populating transaction set with selected packages.

Security updates for software come out all the time, and it's a good idea to keep up-to-date. |
