'''pc-metapkgmanager''' is the back-end command line utility used by the PC-BSD® installer, Update Manager, and Warden® to manage meta-packages. Meta-packages are like system components, and include supported and unsupported desktops, development utilities, hardware drivers, and miscellaneous applications such as MythTV or XBMC.
Beginning with version 9.1, PC-BSD® uses metapkgsets to determine which system components are available and which applications are installed with each system component. Currently, two metapkgsets are available: ''pcbsd'' which defines the available desktop components, and ''warden'' which defines the components available when creating a jail with Warden® or installing a PC-BSD® server. You can view the contents of these metapkgsets on {{citelink|url=http://trac.pcbsd.org/browser/pcbsd/current#build-files/metapkgsets|txt=trac}}.
The '''pc-metapkgmanager''' command can be used at the command line to install or delete meta-packages, update to the latest package set, or to change the default metapkgset. If you type the command without any options, it will display its usage:
usage: pc-metapkgmanager [options]
&nbsp;add pkg1,pkg2 <loc> -- Add the specified list of meta-packages
&nbsp;                          <loc> should be a FTP / HTTP url where pkg_add
&nbsp;                          can fetch packages, or an absolute path to
&nbsp;                          location of pkg files on disk.
&nbsp;checkup -- Check for updates to pkgs
&nbsp;del pkg1,pkg2   -- Delete the specified list of meta-packages
&nbsp;list            -- List the available meta-packages
&nbsp;status <pkg>    -- List the status of the specified meta-packages
&nbsp;update pkg,pkg2 <loc>  -- Update system packages. Can use 'all' or <pkg,pkg2>.
&nbsp;                          <loc> should be a FTP / HTTP url where pkg_add

To view which meta-packages are available in an alternate metapkgset, specify the metapkgset name. For example, to view the available ''warden'' meta-packages from your desktop, use this command:
{{txtbox|box='''pc-metapkgmanager --pkgset warden list {{pipe}} more'''

--More--(byte 989)}}
To permanently change the default metapkgset between ''pcbsd'' and ''warden'', modify the ''PCBSD_METAPKGSET'' variable in ''/usr/local/etc/pcbsd.conf''.
To determine if a meta-package is installed, specify its "Meta Package" name as shown in the output of the '''pc-metapkgmanager list''' command. For example, to see if the Awesome desktop is installed:
{{txtbox|box='''pc-metapkgmanager status Awesome'''
The meta-pkg Awesome is not installed}}
To install the meta-package, use the '''add''' option and specify the meta-package name. Only the superuser can install meta-packages.
The following example installs the Awesome meta-package. '''pc-metapkgmanager''' will provide messages regarding the status of the installation:
{{txtbox|box='''pc-metapkgmanager add Awesome'''

To delete an installed meta-package, specify its name. Only the superuser can uninstall meta-packages. As seen in the following example, '''pc-metapkgmanager''' automatically determines which dependent packages are still needed by other applications and which can be safely removed.

=== Upgrading Meta-Packages === <!--T:19-->
'''pc-metapkgmanager''' can also be used to determine if any meta-packages are out of date and to update meta-packages. To determine if any meta-packages have newer versions:
{{txtbox|box='''pc-metapkgmanager checkup'''
All packages are up to date!}}
In this example, all meta-packages are at their latest versions. If any were out of date, you would instead receive the message "The following package updates are available:" followed by the names of the out-of-date meta-packages.
To update a meta-package, use the '''pc-metapkgmanager update''' command followed by the name of the specific meta-package or the word '''all''' to update all out-of-date meta-packages.
'''pc-metapkgmanager''' records any error messages to ''/tmp/.pc-metamanager.log''. This log file automatically rotates whenever it reaches 5MB in size.

(Sorry for the inconvenience)

PC-BSD® 9.2 added a graphical Package Manager utility to Control Panel which can be used to manage installed desktops and system components. It can also be used as a front-end to the FreeBSD packages collection. The advantage of installing software using this utility is that any software installed this way will be tracked by Update Manager. If you prefer to start this utility from the command line, type pc-su pc-pkgmanager.

Figure 7.2a shows Package Manager with its categories expanded. This sample system uses NVIDIA for graphics and the default desktop manager of KDE was kept during the installation. This default view is known as Basic View.

Figure 7.2a: Viewing Installed Components

To install or uninstall components, check the boxes for the components that you wish to install, uncheck the boxes for the components that you wish to remove, then click the "Apply" button to perform the requested operations.

To instead manage FreeBSD packages, click View ➜ Advanced to change to Advanced View. This view is shown in Figure 7.2b with the editors category expanded.

Figure 7.2b: Managing FreeBSD Packages

The search utility can be used to find packages to install. Alternately, if you know the software category, expand it and check the software you would like to install. As you browse, you can select multiple packages. If you click an application name, its Package Information screen will display, as seen in the example in Figure 7.2c.

Figure 7.2c: Viewing a Package's Information

The Package Information is divided into three tabs:

  • Description: displays the name and version of the package, its download size, the URL to its homepage, and a brief description.
  • Options: shows the options compiled into the package. Options will be listed as either on or off.
  • Dependencies: lists any additional packages that will be installed as dependencies of the selected package.

Once you have made your selections, click the "Apply" button to install the selected software.
