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".

PATH SPECIFICATION

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/admin

In 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/admin

If 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:\/Users

All pathnames are case-sensitive.

COMMANDS

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.

read (cat .)

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.

readall

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.

readpl

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.

readpli

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.

list (ls)

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.

search

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.

create (mk)

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.

createpl

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.

createpli

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.

append

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.

merge

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.

change

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.

changei

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.

diff

Usage: diff path1 path2 key ...

Compares the data from path1 and path2 looking at the specified keys (or all if no keys are specified).

delete (rm)

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.

deletepl

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.

deletepli

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.

passwd

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.

INTERACTIVE COMMANDS

cd

Usage: cd dir

Sets the current directory. Path names for other dscl commands may be relative to the current directory.

pushd (pd)

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.

popd

Usage: popd

Pops the directory stack and returns to the new top directory. It will also print the final directory stack.

auth (su)

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.

authonly

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.
