The pc-updatemanager command can be used to perform an operating system upgrade from the command line. It can also be used to apply system updates and to update non-PBI software.

If you type the command without any options, it will show its available options:

pc-updatemanager
/usr/local/bin/pc-updatemanager - Usage
----
 branches              - List available system branches
 chbranch <tag>        - Change to new system branch
 check                 - Check for system updates
 install <tag>,<tag2>  - Install system updates
 pkgcheck              - Check for updates to packages
 pkgupdate             - Install packages updates

Upgrading Packages

To determine if newer versions of packages are available, type the following command as the superuser.

pc-updatemanager pkgcheck
Updating repository catalogue
Upgrades have been requested for the following 253 packages:
list of packages snipped
The upgrade will require 70 MB more space
439 MB to be downloaded
To start the upgrade run "/usr/local/bin/pc-updatemanager pkgupdate"

In this example, newer versions are available for 253 packages. The list of package names was snipped from the sample output. If no updates were available, the output would have instead said "All packages are up to date!".

If updates are available, you can install them with this command:

pc-updatemanager pkgupdate
Updating repository catalogue
snip downloading and reinstalling output
[253/253] Upgrading pcbsd-base from 1374071964 to 1378408836... done
Extracting desktop overlay data...DONE

While the output has been snipped from this example, the update process will download the latest versions of the packages which need updating, displaying the download progress for each file. Once the downloads are complete, it will display the reinstallation process for each file. The last step of the update process is to extract the desktop (or server) overlay and then to return the prompt.

How long the package upgrade takes depends upon the number of packages and the speed of the Internet connection. If you run this command on a desktop, you should log out and log in again so that you load the latest version of the desktop and its applications. If you run this command on a server while running the tcsh shell, type rehash in order to tell the shell that new applications have been installed.

Applying System Updates

, become the superuser and use the following command to check to see if an update is available:

pc-updatemanager check

The following updates are available: ------------------------------------ NAME: System Update to 9.1 TYPE: SYSUPDATE VERSION: 9.1 DATE: 2012-12-03 TAG: release-9.1 DETAILS: http://www.pcbsd.org

To install this update run "/usr/local/bin/pc-updatemanager install release-9.1"

Follow the instructions to install the update:

Upgrading the Operating System

NOTE: before performing any upgrade, be sure to backup your important data. You should also be aware of the caveats listed here.

The upgrade will then proceed as usual and you will be prompted when the system is ready to reboot.
