NAME

       svcprop - retrieve service configuration properties

SYNOPSIS

       svcprop [-fqtv] [-C | -c | -s snapshot] [-p  [name/]name]... [FMRI | pattern]...

       svcprop -w [-fqtv] [-p  [name/]name] {FMRI | pattern}

       The svcprop utility prints values of properties in the service configuration repository. Properties are selected by -p options and FMRI op-
       erands.

       By default, when a single property is selected, its values are printed separated by spaces on a single line. Empty ASCII string values  are
       represented  by	a  pair  of  double quotes (""). Bourne shell metacharacters (';', '&', '(', ')', '|', '^', '<', '>', newline, space, tab,
       backslash, '"', single-quote, '`') in ASCII string values are quoted by backslashes ().

       When multiple properties are selected, a single line is printed for each. Each line comprises a property designator, a property	type,  and
       the  values (as described above), separated by spaces. By default, if a single FMRI operand has been supplied, the property designator con-
       sists of the property group name and the property name joined by a slash (/). If multiple FMRI operands are supplied, the designator is the
       canonical FMRI for the property.

       A  composed property may be selected directly from the entities which match a specified FMRI or from entities which may be used as a source
       of properties for these matching entities. An example of a composed property is a property which is set on a service, which may be selected
       when an instance matching an FMRI does not possess the property itself.

       An  un-composed	property  selection is made against the specified FMRI with no further searching of additional sources of properties other
       than the entities which match the designated FMRI.

       Properties are displayed either with or without composition depending on the options which are supplied at invocation. Properties are  com-
       posed by default.

       A  snapshot, which is a point in time representation of the state of a matching entity's properties at a moment in time, always uses compo-
       sition because snapshots are always composed.

       Error messages are printed to the standard error stream.

       Many properties have specific meanings to the Service Management Facility or the service's restarter.

       The following options are supported:

       -C		       Retrieves the current property values, without composition.

       -c		       Retrieves the current property values, with composition.

       -f		       Designates properties by their FMRIs. Implies option -t.

       -p [name/]name	       Prints values of the named property or property group for each of the property groups, instances, or services spec-
			       ified by the operands.

       -q		       Quiet. Produces no output.

       -s snapshot	       Uses the named snapshot to retrieve the specified property or property group, with composition (since snapshots are
			       always composed). If the given property group is not present in the snapshot, the current property values are exam-
			       ined.

       -t		       Uses the multi-property output format.

       -v		       Verbose. Prints error messages for nonexistent properties, even if option -q is also used.

       -w		       Waits for the selected property group or property to change before printing anything.

			       This  option  is only valid when a single entity is given. If more than one operand is given, or an operand matches
			       more than one instance, an error message is printed and no action is taken. The -w option always causes svcprop	to
			       operate against current property values.

       The following operand is supported:

       FMRI	       With  no  -p  options,  FMRI  operands  can  name  a  service, instance, property group, or property. For services, service
		       instances, and property groups, all contained properties are selected.

		       Instances and services can be abbreviated by specifying the instance name, or the trailing portion  of  the  service  name.
		       Properties and property groups must be specified by a full FMRI. For example, given the FMRI:

		       svc:/network/smtp:sendmail

		       The following are valid abbreviations:

		       sendmail
		       :sendmail
		       smtp
		       smtp:sendmail
		       network/smtp

		       The following are invalid abbreviations:

		       mail
		       network
		       network/smt

		       Abbreviated forms of FMRIs are unstable and should not be used in scripts or other permanent tools.

		       Arguments  to  the  -p  option  can  name  property groups or properties. In the former case, operands can name services or
		       instances, and all properties in the named property group of the named services or instances are printed.  In  the  latter,
		       operands can name services, instances, or property groups, and the named properties belonging to the operands are printed.

		       By  default, all properties are selected from the running snapshot, with composition. If there is no running snapshot, then
		       current properties are selected. The -w and -s options can be used to change the source of properties.

		       When walking properties, that is, no -p options, current nonpersistent property groups are also selected.

		       With -p options, if the property group doesn't exist in the running snapshot, then if the property group  is  nonpersistent
		       the current property or property group is selected.

       Example 1: Displaying the Value of a Single Property

       The following example displays the value of the enabled property in the general property group of instance default of service inetd.

       example%  svcprop -p general/enabled network/inetd:default
       true

       Example 2: Displaying All Properties in a Property Group

       This example displays all properties in the general property group of service ntp.

       example% svcprop -p general ntp
       general/entity_stability astring Unstable
       general/single_instance boolean true

       Example 3: Verifying the Existance of a Property

       This example verifies the existence of the general/enabled property for all instances of service identity.

       example%  svcprop -q -p general/enabled identity:
       example%  echo $?
       0

       Example 4: Waiting for Property Change

       This example waits for the sendmail instance to change state.

       example%  svcprop -w -p restarter/state sendmail

       Example 5: Using svcprop in a Script

       example% cat getval
       #!/bin/sh

       svcprop -p $1 $2 | (
		read value v2
		if [ -n "$v2" ]; then echo "Multiple values!"; exit; fi
		echo $value
	      )

       The following exit values are returned:

       0	Successful completion.

       1	An error occurred.

       2	Invalid command line options were specified.
