dscl is a general-purpose utility for
operating on Directory Service directory nodes. Its commands allow one to
create, read, and manage Directory Service data. If invoked without any
commands, dscl runs in an interactive mode, reading
commands from standard input. Interactive processing is terminated by the
quit command. Leading dashes ("-") are
optional for all commands.
dscl operates on a datasource specified on
the command line. This may be a node name or a Mac OS X Server (10.2 or
later) host specified by DNS hostname or IP address. Node names may be
absolute paths beginning with a slash ("/"), or relative domain
paths beginning with a dot (".") character, which specifies the
local domain, or "..", specifying the local domain's parent. If
the hostname or IP address form is used then the user must specify the
-u option and either the -P
or -p options to specify an administrative user and
password on the remote host to authenticate with to the remote host. The
exception to this is if "localhost" is specified. Passing
passwords on the command line is inherently insecure and can cause password
exposure. For better security do not provide the password as part of the
command and you will be securely prompted.
The datasource may also be specified as "localonly" in
which case a separate DirectoryService daemon process is activated which
contains only the Local plugin for use by dscl. If no file path is provided
then access goes only to the registered local nodes on the system. However,
if the -f option is specified then access is added
to the local node "/Local/Target" which points to the database
located at the provided filepath. One example is to provide the filepath of
"/Volumes/Build100/var/db/dslocal/nodes/Default" and then access
to that database is provided via the nodename "/Local/Target".
There are two modes of operation when specifying paths to operate on. The two modes correspond to whether the datasource is a node or a host. In the case of specifying a node, the top level of paths will be record types. Example top level paths would be:
/Users/alice/Groups/adminIn the case of specifying a host as a data source, the top level of paths correspond to Open Directory plug-ins and Search Paths. One can specify the plug-in to traverse to a node name, after which the paths are equivalent to the former usage. The following might be the equivalent paths as the above paths:
/NetInfo/root/Users/alice/LDAPv3/10.0.1.42/Groups/adminIf path components contain keys or values with embedded slash characters, the slash characters must be escaped with a leading backslash character. Since the shell also processes escape characters, an extra backslash is required to correctly specify an escape. For example, to read a mount record with the name "ldapserver:/Users" in the "/Mounts" path, the following path would be used:
dscl
. -read
/Mounts/ldaphost:\/UsersAll pathnames are case-sensitive.
The action of each command is described below. Some commands have aliases. For example, "cat" and "." are aliases for "read". Command aliases are listed in parentheses.
Usage: read [path [key
...]]
Prints a directory. The property key is followed by colon, then a space-separated list of the values for that property. If any value contains embedded spaces, the list will instead be displayed one entry per line, starting on the line after the key.
If The -raw flag for raw output has been
given, then read prints the full
DirectoryService API constant for record and attribute types.
If the -url flag has been specified then
printed record path attribute values are encoded in the style of URLs. This
is useful if a script or program is trying to process the output since
values will not have any spaces or other control characters.
Usage: readall [path
[key ...]]
readall prints all the records of a given type. The output of readall is formatted in the same way as read with a "-" on a line as a delimeter between records.
Usage: readpl path key plist_path
Prints the contents of plist_path. The plist_path is followed by a colon, then a whitespace, and then the value for the path.
If the plist_path is the key for a dictionary or array, the contents of it are displayed in plist form after the plist_path. If plist_path is the key for a string, number, bool, date, or data object, only the value is printed out after the plist_path.
Usage: readpli path key value_index plist_path
Prints the contents of plist_path for the plist at value_index of the key. The plist_path is followed by a colon, then a whitespace, and then the value for the path.
If the plist_path is the key for a dictionary or array, the contents of it are displayed in plist form after the plist_path. If plist_path is the key for a string, number, bool, date, or data object, only the value is printed out after the plist_path.
Usage: list path
Lists the subdirectories of the given directory. Subdirectories are listed one per line. In the case of listing a search path, the names are preceded by an index number that can act as a shortcut and used in place of the name when specifying a path.
When used in interactive mode, the path is optional. With no path given, the current directory will be used.
path key val
Searches for records that match a pattern. The search is rooted at the given path. The path may be a node path or a record type path. Valid keys are Directory Service record attribute types.
Usage: create record_path
[key [val
...]]
Creates a record, property, or value. If only a record path is given, the create command will create the record if it does not exist. If a key is given, then a property with that key will be created.
WARNING - If a property with the given key already exists, it will be destroyed and a new property will be created in its place. To add values to an existing property, use the append or merge commands.
If values are included in the command, these values will be set for the given key.
NOTE - Not all directory nodes support a property without a value. An error will be given if you attempt to create a property with no value in such a directory node.
Usage: createpl record_path
key plist_path
val1 [val2
...]
Creates a string, or array of strings at plist_path.
If you are creating a value at the root of a plist that is an array, simply use "0" as the plist_path.
If only val1 is specified, a string will be
created at plist_path. If val1
val2 ... are specified, an array of strings
will be created at plist_path.
WARNING - If a value with the given plist_path already exists, it will be destroyed and a new value will be created in its place.
Usage: createpli record_path
key value_index
plist_path val1
[val2 ...]
Creates a string, or array of strings at plist_path for the plist at value_index of the key.
If you are creating a value at the root of a plist that is an array, simply use "0" as the plist_path.
If only val1 is specified, a string will be
created at plist_path. If val1
val2 ... are specified, an array of strings
will be created at plist_path.
WARNING - If a value with the given plist_path already exists, it will be destroyed and a new value will be created in its place.
Usage: append record_path key val
...
Appends one or more values to a property in a given record. The property is created if it does not exist.
Usage: merge record_path key val
...
Appends one or more values to a property in a given directory if the property does not already have those values. The property is created if it does not exist.
Usage: change record_path key old_val new_val
Replaces the given old value in the list of values of the given key with the new value in the specified record.
Usage: changei path key index val
Replaces the value at the given index in the list of values of the given key with the new value in the specified record. index is an integer value. An index of 1 specifies the first value. An index greater than the number of values in the list will result in an error.
Usage: diff path1 path2 key
...
Compares the data from path1 and path2 looking at the specified keys (or all if no keys are specified).
Usage: delete path
[key [val
...]]
Delete a directory, property, or value. If a directory path is given, the delete command will delete the directory. This can only be used on record type and record paths. If a key is given, then a property with that key will be deleted. If one or more values are given, those values will be removed from the property with the given key.
Usage: deletepl record_path
key plist_path [val
...]
Deletes a value in a plist. If no values are given deletepl deletes the plist_path. If one or more values are given, deletepl deletes the values within plist_path.
Usage: deletepli record_path
key value_index
plist_path [val ...]
Deletes a value for the plist at value_index of the key. If no values are given deletepli deletes the plist_path. If one or more values are given, deletepli deletes the values within plist_path.
Usage: passwd user_path [new_password | old_password new_password]
Changes a password for a user. The user must be specified by full
path, not just a username. If you are authenticated to the node (either by
specifying the -u and -P
flags or by using the auth command when in interactive node) then you can
simply specify a new password. If you are not authenticated or if FileVault
is enabled then the user's old password must be specified. If passwords are
not specified while in interactive mode, you will be prompted for them.
Passing these passwords on the command line is inherently insecure and can
cause password exposure. For better security do not provide the password as
part of the command and you will be securely prompted.
Usage: cd dir
Sets the current directory. Path names for other
dscl commands may be relative to the current
directory.
Usage: pushd path
Similar to the pushd command commonly found in Unix shells. When a path is specified it sets the current directory while pushing the previous directory on to the directory stack. If no path is specified it exchanges the top two elements of the directory stack. It will also print the final directory stack.
Usage: popd
Pops the directory stack and returns to the new top directory. It will also print the final directory stack.
Usage: auth [user [password]]
Authenticate as the named user, or as "root" if no user is specified. If a password is supplied, then that password is used for authentication, otherwise the command prompts for a password.
If dscl is run in host mode, then when
this command is run the current directory must be in the subdirectories of a
node.
Usage: authonly [user [password]]
Used to verify the password of a named user, or of "root" if no user is specified. If a password is supplied, then that password is used for authentication, otherwise the command prompts for a password.
If dscl is run in host mode, then when
this command is run the current directory must be in the subdirectories of a
node.
Usage: quit
Ends processing of interactive commands and terminates the program.
The up and down arrow keys will scan through the command history.
When pathnames are being typed, pressing the tab key will result in a search to auto-complete the typed partial subdirectory name. It will also attempt to correct capitilization in the process.
