SCUTIL(8) BSD System Manager's Manual SCUTIL(8)
NAME
scutil -- Manage system configuration parameters
SYNOPSIS
scutil
scutil --prefs [preference-file]
scutil -r [-W] { nodename | address | local-address remote-address }
scutil -w dynamic-store-key [-t timeout]
scutil --get pref
scutil --set pref [newval]
scutil --dns
scutil --proxy
DESCRIPTION
Invoked with no options, scutil provides a command line interface to the "dynamic store" data main-tained maintained
tained by configd(8). Interaction with this data (using the SystemConfiguration.framework SCDynamic-Store SCDynamicStore
Store APIs) is handled with a set of commands read from standard input. A list of the available com-mands commands
mands is available by entering the help directive.
The --prefs option provides a command line interface to the [raw] stored preference data. Interaction
with this data (using the SystemConfiguration.framework SCPreferences APIs) is handled with a set of
commands read from standard input. A list of the available commands is availble by entering the help
directive.
The -r option provides a means of checking the network reachability of a host, an IP address, or a pair
of local and remote IP addresses. Network "reachability" is a term that indicates whether network com-munication communication
munication is possible between the current host and the specified host.
The -w option provides a means of checking for (and optionally waiting for the creation of or posting
of a notification to) a dynamic store key.
The --get and --set options provide a means of reporting and updating a select group of persistent sys-tem system
tem preferences.
The --dns option reports the current DNS configuration. The first listed resolver(5) configuration is
considered to be the "default" configuration. Additional "supplemental" configurations follow. Those
containing a "domain" name will be used for queries matching the specified domain. Those without will
be used as a "default" configuration in addition to the first listed.
The --proxy option reports the current system proxy configuration.
OPTIONS
-r [-W] { nodename | address | local-address remote-address }
Check the network reachability of the specified host name, IP address, or a pair of local and
remote IP addresses. One or more of the following strings will be reported to standard output.
Not Reachable The specified nodename/address cannot be reached using the current network
configuration.
Reachable The specified nodename/address can be reached using the current network con-figuration. configuration.
figuration.
Transient Connection The specified nodename/address can be reached via a transient (e.g. PPP) con-nection. connection.
nection.
Connection Required The specified nodename/address can be reached using the current network con-figuration configuration
figuration but a connection must first be established. As an example, this
status would be returned for a dialup connection that was not currently
active but could handle network traffic for the target system.
Connection Automatic The specified nodename/address can be reached using the current network con-figuration configuration
figuration but a connection must first be established. Any traffic directed
to the specified name/address will initiate the connection.
Local Address The specified nodename/address is one associated with a network interface on
the system.
Directly Reachable Addresss
Network traffic to the specified nodename/address will not go through a gate-way gateway
way but is routed directly to one of the interfaces on the system.
The reachability can also be monitored by specifying the -W (watch) option. This will result in
the current status being reported as well as the status when/if the network configuration changes.
A zero exit status will be returned when the reachability status is reported correctly. A non-zero
exit status will be returned if errors are detected with an error reported to standard error.
-w dynamic-store-key [-t timeout]
Check if the specified key exists in the "dynamic store" data maintained by configd(8). If
present, scutil will return with a zero exit status. If not present, scutil will wait for the
specified time for data to be associated with or a notification to be posted using the key. A non-zero nonzero
zero exit status will be returned if the key was not created/posted within the specified time.
scutil will wait indefinitely if a timeout of 0 seconds is specified. The default timeout is 15
seconds.
--get pref
Retrieves the specified preference. The current value will be reported on standard output.
Supported preferences include:
ComputerName The user-friendly name for the system.
LocalHostName The local (Bonjour) host name.
HostName The name associated with hostname(1) and gethostname(3).
--set pref [newval]
Updates the specified preference with the new value. If the new value is not specified on the com-mand command
mand line then it will be read from standard input.
Supported preferences include: ComputerName LocalHostName HostName
The --set option requires super-user access.
--dns
Reports the current DNS configuration.
--proxy
Reports the current proxy configuration.
