- 7.6 at the time of the article is the latest.
- Update is changing to a new minor release.
- Upgrade is changing to a new major release.
Here's we are updating.
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 ver‐ bose mode also shows obsoletes.
update If run without any packages, update will update every currently installed package. If one or more packages or package globs are specified, Yum will only update the listed packages. While updating packages, yum will ensure that all dependencies are satisfied. (See Specify‐ ing package names for more information) If the packages or globs specified match to pack‐ ages which are not currently installed then update will not install them. update operates on groups, files, provides and filelists just like the "install" command. If the main obsoletes configure option is true (default) or the --obsoletes flag is present yum will include package obsoletes in its calculations - this makes it better for dis‐ tro-version changes, for example: upgrading from somelinux 8.0 to somelinux 9. Note that "update" works on installed packages first, and only if there are no matches does it look for available packages. The difference is most noticeable when you do "update foo-1-2" which will act exactly as "update foo" if foo-1-2 is installed. You can use the "update-to" if you'd prefer that nothing happen in the above case.
$ cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core)
check-update option to yum will show if you have any updates available. No output TL.
$ yum check-updates
Update from 7.5 to 7.6 (latest to date). No output TL.
$ sudo yum update
Check release again.
$ cat /etc/redhat-release CentOS Linux release 7.6.1810 (Core)
If nothing needs upgrading then, there's no package listing in the output. This is what you will see after an upgrade.
$ yum check-updates Loaded plugins: fastestmirror, langpacks Determining fastest mirrors * base: mirrors.clouvider.net * extras: mirror.sax.uk.as61049.net * updates: mirror.sax.uk.as61049.net
