Using the yum command with the option:
check-update Implemented so you could know if your machine had any updates that needed to be applied without running it interactively. Returns exit value of 100 if there are packages available for an update. Also returns a list of the packages to be updated in list format. Returns 0 if no packages are available for update. Returns 1 if an error occurred. Running in verbose mode also shows obsoletes.
The command provides a summary at the end.
$ sudo yum check-update --security ... ... ... No packages needed for security; 86 packages available
