NAME

     installer -- system software and package installer tool.

SYNOPSIS

     installer [-dominfo] [-volinfo] [-pkginfo] [-showChoicesXML] [-showChoicesAfterApplyingChangesXML <pathToXMLFile>]
	       [-applyChoiceChangesXML <pathToXMLFile>] [-query <flag>] [-allow] [-dumplog] [-help] [-verbose | -verboseR] [-vers] [-config]
	       [-plist] [-file <pathToFile>] [-lang <ISOLanguageCode>] [-listiso] -package <pathToPackage> -target device

DESCRIPTION

     The installer command is used to install Mac OS X installer packages to a specified domain or volume.  The installer command installs a sin-
     gle package per invocation, which is specified with the -package parameter ( -pkg is accepted as a synonym).  It may be either a single pack-
     age or a metapackage.  In the case of the metapackage, the packages which are part of the default install will be installed unless disquali-
     fied by a package's check tool(s).

     The target volume is specified with the -target parameter ( -tgt is accepted as a synonym).  It must already be mounted when the installer
     command is invoked.

     For system software installs, the target volume must be a different volume than the one currently running the booted system.  See systemsetup
     (only available on Mac OS X Server) to set the boot volume.

     The installer command requires root privileges to run.  If a package requires authentication (set in a package's .info file) the installer
     must be either run as root or with the sudo(8) command (but see further discussion under the -store option).

     The installer is not responsible for rebooting the machine after installing.  Use reboot(8) or shutdown(8) -r now to reboot the system.

     The installer displays two forms of output.  The default terse output is intended for parsing by scripting languages for automating (or
     scripting) installs and verbose output providing additional information and descriptive error messages.

     A list of flags and their descriptions:

     -dominfo
	     Displays a list of domains into which the software package can be installed.  For example: LocalSystem or CurrentUserHomeDirectory.
	     The domains listed are those which are available and enabled when the command is run.

     -volinfo
	     Displays a list of volumes onto which the software package can be installed.  The volumes listed are the mounted volumes available
	     when the command is run.

     -pkginfo
	     Displays a list of packages that can be installed onto the target volume.	If a metapackage is given as the package source, all of
	     its subpackages are listed.

     -query flag
	     Queries a package for information about the metadata.  See -help for supported flags.

     -allowUntrusted
	     Allow install of a package signed by an untrusted (or expired) certificate.

     -dumplog
	     Detailed log information is always sent to syslog using the LOG_INSTALL facility (and will wind up in /var/log/install.log).
	     -dumplog additionally writes this log to standard error output.

     -help   Displays the help screen describing the list of parameters.

     -verbose
	     Displays more descriptive information than the default output.  Use this parameter in conjunction with -pkginfo and -volinfo informa-
	     tion requests to see more readable output.  The default output is formatted for scripting.

     -verboseR
	     Displays same information as -verbose except the output is formatted for easy parsing.

     -vers   Displays the version of this command.

     -config
	     Formats the command line installation arguments for later use.  The output is sent to stdout, but can be redirected to a file to cre-
	     ate a configuration file.	When specifying this option, an installation is not actually performed.  This configuration file can be
	     supplied as the argument to the -file parameter instead of typing a long series of installation arguments.  The config file can be
	     used to perform multiple identical installs.  You can create a config file as follows:

	     installer -pkg ~/Documents/Foo.pkg -target / -config > /tmp/configfile.plist

     -plist  Formats the installer output into an XML file, which is sent by default to stdout.  Use this parameter for -dominfo, -volinfo, and
	     -pkginfo

     -file pathToFile
	     Specifies the path to the XML file containing parameter information in the key/value dictionary.  This file can be used instead of
	     the command line parameters, and supersedes any parameters on the command line.  When you type this parameter, you type the path to
	     the XML file.  Use with config file generated by -config For example:

	     installer -file /tmp/configfile.plist

     -lang ISOLanguageCode
	     Default language of installed system (ISO format).  This is only necessary when performing a system (OS) install, otherwise is it
	     ignored.  There is no verification done to make sure that the language being set actually exists on the machine, however the ISO lan-
	     guage code is verified to ensure that it is valid.

     -listiso
	     Display the list of valid ISO language codes the installer recognizes.

     -showChoiceChangesXML
	     Prints to stdout the install choices for the package (specified with -pkg) in an XML format. This allows choice attributes to be mod-
	     ified and applied at install-time using -applyChoiceChangesXML.  See CHOICE CHANGES FILE for details of this XML format.

     -applyChoiceChangesXML pathToXMLFile
	     Applies the install choice changes specified in pathToXMLFile to the default choices in the package before installation. This allows
	     the command-line installer to customize choice what gets installed. See CHOICE CHANGES FILE for details of this XML format. Any prob-
	     lems encountered while applying the choice changes will be reported to the LOG_INSTALL facility (i.e. to /var/log/install.log), and
	     also to stdout if -dumplog is used.

     -showChoicesAfterApplyingChangesXML pathToXMLFile
	     Applies the install choice changes specified in pathToXMLFile to the default choices in the package, and then dumps the resulting
	     choice state to stdout.  The input and output XML format is as described in CHOICE CHANGES FILE.  Since changing one choice in a
	     package can implicitly change other choices, this option allows you to confirm that a particular choiceChanges file will have the
	     intended effect. You must specify a -target when using this option, since the evaluated choices can also change with the state of the
	     target disk.

     -showChoicesXML
	     Prints to stdout the install choices for the package (specified with -pkg) in a hierarchical XML format. This is not the same format
	     as used with -applyChoiceChangesXML.  This option is provided for System Image Utility only.

     -store  Install the product archive specified by -package, in the same way that it would be installed through the Mac App Store. In this
	     mode, no other options are supported. (You can specify -target, but the only allowable value is the root volume mount point, /). For
	     best Mac App Store fidelity, run installer as an admin user (not using sudo); you will prompted for your admin user's password before
	     the install begins.

	     This mode is provided for testing a product archive before submission to the Mac App Store. See productbuild(1) for how to create a
	     product archive.

DEVICES

     A device parameter for the target is any one of the following:

     1) Any of the values returned by -dominfo
     2) The device node entry.	Any entry of the form of /dev/disk*.  ex: /dev/disk2
     3) The disk identifier.  Any entry of the form of disk*.  ex: disk1s9
     4) The volume mount point.  Any entry of the form of /Volumes/Mountpoint.	ex: /Volumes/Untitled
     5) The volume UUID.  ex: 376C4046-083E-334F-AF08-62FAFBC4E352

CHOICE CHANGES FILE

     A ``choiceChanges'' file allows individual installer choices to be selected or deselected. A template choiceChanges file for a given package
     can be generated with the -showChoiceChangesXML option, and is interpreted as follows.

     The choiceChanges file is a property list containing an array of dictionaries. Each dictionary has the following three keys:

     Key		 Description
     choiceIdentifier	 Identifier for the choice to be modified (string)
     choiceAttribute	 One of the attribute names described below (string)
     attributeSetting	 A setting that depends on the choiceAttribute, described below (number or string)

     The choiceAttribute and attributeSetting values are as follows:

     choiceAttribute	 attributeSetting Description
     selected		 (number) 1 to select the choice, 0 to deselect it
     enabled		 (number) 1 to enable the choice, 0 to disable it
     visible		 (number) 1 to show the choice, 0 to hide it
     customLocation	 (string) path at which to install the choice (see below)

     Note that there can be multiple dictionaries for the same choiceIdentifier, since there can be multiple attributes set for a single choice.

     The customLocation attribute can be set for a choice only if that choice explicitly allows a user-defined path. That is, if the choice would
     have a Location popup when viewed in the Customize pane of the Installer application, it can be set via customLocation.  (Otherwise, instal-
     lation paths cannot be arbitrarily modified, since the package author must account for custom install locations for the installation to work
     properly.)
