NAME
defaults -- access the Mac OS X user defaults system

SYNOPSIS
defaults [-currentHost | -host hostname] read [domain [key]]

defaults [-currentHost | -host hostname] read-type domain key

defaults [-currentHost | -host hostname] write domain { 'plist' | key
'value' }

defaults [-currentHost | -host hostname] rename domain old_key new_key

defaults [-currentHost | -host hostname] delete [domain [key]]

defaults [-currentHost | -host hostname] { domains | find word | help }

DESCRIPTION
Defaults allows users to read, write, and delete Mac OS X user defaults
from a command-line shell. Mac OS X applications and other programs use
the defaults system to record user preferences and other information that
must be maintained when the applications aren't running (such as default
font for new documents, or the position of an Info panel). Much of this
information is accessible through an application's Preferences panel, but
some of it isn't, such as the position of the Info panel. You can access
this information with defaults

Note: Since applications do access the defaults system while they're run-
ning, you shouldn't modify the defaults of a running application. If you
change a default in a domain that belongs to a running application, the
application won't see the change and might even overwrite the default.

User defaults belong to domains, which typically correspond to individual
applications. Each domain has a dictionary of keys and values represent-
ing its defaults; for example, "Default Font" = "Helvetica". Keys are
always strings, but values can be complex data structures comprising
arrays, dictionaries, strings, and binary data. These data structures are
stored as XML Property Lists.

Though all applications, system services, and other programs have their
own domains, they also share a domain named NSGlobalDomain. If a default
isn't specified in the application's domain, but is specified in
NSGlobalDomain, then the application uses the value in that domain.

The commands are as follows:

read Prints all of the user's defaults, for every domain, to
standard output.

read domain Prints all of the user's defaults for domain to standard
output.

read domain key
Prints the value for the default of domain identified by
key.

read-type domain key
Prints the plist type for the given domain identified by
key.

write domain key 'value'
Writes value as the value for key in domain. value must be
a property list, and must be enclosed in single quotes. For
example:

defaults write com.companyname.appname "Default Color" '(255, 0, 0)'

sets the value for Default Color to an array containing the
strings 255, 0, 0 (the red, green, and blue components).
Note that the key is enclosed in quotation marks because it
contains a space.

write domain 'plist'
Overwrites the defaults information in domain with that
given as plist. plist must be a property list representa-
tion of a dictionary, and must be enclosed in single quotes.
For example:

defaults write com.companyname.appname '{ "Default Color" = (255, 0, 0);
"Default Font" = Helvetica; }';

erases any previous defaults for com.companyname.appname and
writes the values for the two names into the defaults sys-
tem.

delete domain
Removes all default information for domain.

delete domain key
Removes the default named key from domain.

domains Prints the names of all domains in the user's defaults sys-
tem.

find word Searches for word in the domain names, keys, and values of
the user's defaults, and prints out a list of matches.

help Prints a list of possible command formats.

OPTIONS
Specifying domains:

domain If no flag is specified, domain is a domain name of the form
com.companyname.appname. Example:

defaults read com.apple.TextEdit

-app application
The name of an application may be provided instead of a domain
using the -app flag. Example:

defaults read -app TextEdit

filepath Domains may also be specified as a path to an arbitrary plist
file, with or without the '.plist' extension. For example:

defaults read ~/Library/Containers/com.apple.TextEdit/Data/Library/Preferences/com.apple.TextEdit.plist

normally gives the same result as the two previous examples.
In the following example:

defaults write ~/Desktop/TestFile foo bar

will write the key 'foo' with the value 'bar' into the plist
file 'TestFile.plist' that is on the user's desktop. If the
file does not exist, it will be created. If it does exist, the
key-value pair will be added, overwriting the value of 'foo' if
it already existed.

WARNING: The defaults command will be changed in an upcoming
major release to only operate on preferences domains. General
plist manipulation utilities will be folded into a different
command-line program.

-g | -globalDomain | NSGlobalDomain
Specify the global domain. '-g' and '-globalDomain' may be used
as synonyms for NSGlobalDomain.

Specifying value types for preference keys:

If no type flag is provided, defaults will assume the value
is a string. For best results, use one of the type flags,
listed below.

-string Allows the user to specify a string as the value for the
given preference key.

-data Allows the user to specify a bunch of raw data bytes as the
value for the given preference key. The data must be pro-
vided in hexidecimal.

-int[eger] Allows the user to specify an integer as the value for the
given preference key.

-float Allows the user to specify a floating point number as the
value for the given preference key.

-bool[ean] Allows the user to specify a boolean as the value for the
given preference key. Value must be TRUE, FALSE, YES, or NO.

-date Allows the user to specify a date as the value for the given
preference key.

-array Allows the user to specify an array as the value for the
given preference key:

defaults write somedomain preferenceKey -array element1 element2 element3

The specified array overwrites the value of the key if the
key was present at the time of the write. If the key was not
present, it is created with the new value.

-array-add Allows the user to add new elements to the end of an array
for a key which has an array as its value. Usage is the same
as -array above. If the key was not present, it is created
with the specified array as its value.

-dict Allows the user to add a dictionary to the defaults database
for a domain. Keys and values are specified in order:

defaults write somedomain preferenceKey -dict key1 value1 key2 value2

The specified dictionary overwrites the value of the key if
the key was present at the time of the write. If the key was
not present, it is created with the new value.

-dict-add Allows the user to add new key/value pairs to a dictionary
for a key which has a dictionary as its value. Usage is the
same as -dict above. If the key was not present, it is cre-
ated with the specified dictionary as its value.

Specifying a host for preferences:

Operations on the defaults database normally apply to any host the user
may log in on, but may be restricted to apply only to a specific host.

If no host is provided, preferences operations will apply to
any host the user may log in on.

-currentHost
Restricts preferences operations to the host the user is cur-
rently logged in on.

-host hostname
Restricts preferences operations to hostname.

BUGS
Defaults can be structured in very complex ways, making it difficult for
the user to enter them with this command.
