Yum Checking for updated

Checking For Updates

To see which installed packages on your system have updates available, use the following command:

yum check-update

For example:

~]# yum check-update
Loaded plugins: product-id, refresh-packagekit, subscription-manager
Updating Red Hat repositories.
INFO:rhsm-app.repolib:repos updated: 0
PackageKit.x86_64                  0.5.8-2.el6                rhel
PackageKit-glib.x86_64             0.5.8-2.el6                rhel

The packages in the above output are listed as having updates available. The first package in the list is PackageKit, the graphical package manager. The line in the example output tells us:

PackageKit — the name of the package
x86_64 — the CPU architecture the package was built for
0.5.8 — the version of the updated package to be installed
rhel — the repository in which the updated package is located
