     nicl is general-purpose utility for operating on NetInfo databases.  Its commands allow one
     to create, read, and manage NetInfo data.	If invoked without any commands, nicl runs in an
     interactive mode, reading commands from standard input.  Interactive processing is termi-
     nated by the quit command, or by end of file.  Leading dashes ("-") are optional for all

     nicl operates on a datasource specified on the command line.  This may be a domain name, a
     NetInfo server of the form "host/tag", or a file.	Domain names may be absolute paths begin-
     ning 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 -t
     option has been specified, then the datasource is a host/tag specification.  Hosts may be
     given by name or IP address.  If the -raw option has been specified, then the datasource is
     a NetInfo-format database, for example "/var/db/netinfo/local.nidb".  The user invoking nicl
     must have sufficient file-system permissions to read the database files.

     In "raw" mode, nicl operates directly on the database without communicating with a server
     for that database.

     Many commands take a directory as an option.  Directories may be specified as a directory ID
     number or as a path.  NetInfo paths are specified by a list of slash-separated components.
     Each component is of the form:


     In the first form, the key defaults to "name".  Thus the following two paths are equivalent:


     Note that NetInfo does not require any key to have unique values.	When matching a directory
     path, NetInfo will match the first directory it finds with a given key and value.	For exam-
     ple, the following path will locate a user with a gid  of "100":


     Many users may have a gid value of 100.  This path will match the first in some search
     order.  The only unique identifier for NetInfo directories is the directory ID number.  This
     number is printed in the output of the list command, and is printed by the read command if
     the nicl is invoked with the -v (verbose) flag.

     If path components contain keys or values with embedded slash characters, the slash charac-
     ters 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 exam-
     ple, to read a directory with the name "/Alpha" in the "/exports" directory, one of the fol-
     lowing paths could be used:

	   nicl  . -read /exports/\\/Alpha
	   nicl  . -read /exports/name=\\/Alpha

X.500 MODE
     nicl was developed using an internal datastore "engine" with operations supporting both the
     legacy NetInfo network protocol and LDAP Version 3.  Development work is still in progress
     in this area.  Some nicl commands have been written for use in "X.500" mode, invoked by use
     of the -x500 flag.  Support for X.500-style data organization, naming, and access is still
     experimental and under active development.

     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 dir [key ...]

     Prints a directory.  Each properties are printed one per line.  The property key is followed
     by a colon, then a space-separated list of the values for that property.  Note that a value
     which contains embedded spaces will appear identical to a pair of values.	If The -v flag
     for verbose output has been given, then read prints the directory (record) ID number, its
     version number, serial number, a count of child directories and a list of child directory ID
     numbers.  Attributes are printed separately from meta-attributes (those having a leading
     underscore character).

   list (ls)
     Usage: list dir [key]

     Lists the subdirectories of the given directory.  Subdirectories are listed one per line.
     The directory ID number is printed first, then the values of "name" key.  If an optional key
     argument is given, then the values for that key are used, rather than the values for the
     "name" key.

     Note that subdirectories that do not have a "name" key (or the key given as an option) are
     not listed.

     path scopemin scopemax key val [key val] ...

     Searches for directories that match a pattern.  The search is rooted at the given directory.
     The following two arguments control the scope of the search by specifying the starting and
     ending depth of the search.  If scopemin argument is 0, for example, the search will include
     the starting directory itself.  A value of 1 will start searching at the subdirectories of
     the starting directory.  The value of scopemax specifies the maximum depth of the search.	A
     value of 0 stops the search at the starting directory.  A value of 1 stops the search one
     level down.  A value of -1 causes the search to have no maximum depth.

     Following the scope arguments are one or more key and value pairs.  Directories that have
     matching keys and values will be printed.

     Usage: path path

     Prints the directories from the given directory to the root directory.

     Usage: load [delim key val ...] ...

     Creates a child directory of the current directory.  This command allows a directory to be
     created with a number of properties.  The first character given in the input is subsequently
     used as a delimiter to separate key val ... sets.	For example, to create a directory with
     the name "foo", and a property "bar" with the values "a", "b", and "c", and a property "baz"
     with the values "abc" and "def":

	   load + name foo + bar a b c + baz abc def

     Any single character may be used as a delimiter.

   create (mk)
     Usage: create [path [key [val ...]]]

     Creates a new directory, property, or value.  If a directory path is given, the create com-
     mand will create the directory path if it does not exist.	If a key is given, then a prop-
     erty 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.

     If it is invoked without any arguments as a single command-line argument to nicl , the
     create command will create a new database.  For example, to create a new database

	   nicl   -raw /tmp/test_db -create

     The "mk" alias is not available for creating a new database.  Note that a new database may
     also be created by using the -c option on the command line.

     Usage: append path key val ...

     Appends one or more values to a property in a given directory.  The property is created if
     it does not exist.

     Usage: merge 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: insert path key val index Inserts the given value in the list of values of the given
     key in the specified directory.  index is an integer value.  An index of 0 specifies that
     the value should be inserted at the head of the list.  An index greater than the number of
     values in the list causes the value to be appended.  The property is created if it does not

     Usage: rename path old_key new_key

     Changes a property key.

   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.  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.

   copy (cp)
     Usage: copy path new_parent

     Recursively copies a directory to a new parent directory.

   move (mv)
     Usage: move path new_parent

     Moves a directory to a new parent directory.  In raw mode, move moves a directory by detach-
     ing it from its parent directory and re-attaching it to a new parent.  When connected to a
     NetInfo server, the directory is recursively copied to the new parent directory, then the
     original is removed.

   history (hist)
     Usage: history [<=>] [version]

     Locates directories by reference to the database version number.  When a new database is
     created, it starts with a version number of zero.	Each modification of the database causes
     the version number to be incremented.  The database version number is saved with the direc-
     tory that was modified at that time.  When a directory is added or removed, the parent
     directory is modified, and thus the parent directory carries the version number for that

     The history command lists directories that have been modified before, at, or after a spe-
     cific version of the database.   The < argument is used to locate directories that changed
     before a specific version.  The > argument locates directories that changed after a specific
     version.  The = after locates the single directory that changed at a specific version.  This
     is also the default if none of these arguments is given.

     If a version number is omitted, the current database version number is used.  To determine
     the current database version:

	   nicl  . -history

   statistics (stats)
     Usage: statistics

     Prints various statistics.  If the datasource is a raw database this includes the database
     checksum, version number, maximum directory ID number, and counts of fetch, save, and remove
     operations.  If the datasource is a NetInfo server, then this command prints all statistics
     available from the server.

   domainname (name)
     Usage: domainname

     Prints the NetInfo domain name.  Not available in raw mode.

     Usage: rparent

     Prints the IP address and tag of the server's parent domain server.  No output is printed if
     the server has no parent.	Not available in raw mode.

     Usage: resync

     If connected to a NetInfo clone server, this command causes the clone to check its database
     and re-synchronize with the master if necessary.  If connected to a master server, this com-
     mand causes the master to send a message to all clones, causing them all to re-synchronize.
     Not available in raw mode.

     Usage: flush

     Flushes the directory cache.

     Usage: echo string

     Prints the string to standard output.  This is handy when executing a script.

   source (<)
     Usage: source file

     Redirects standard input to read commands from the named file.  After the commands in the
     file have been processed, control returns to the command line (if invoked interactively).

     Usage: cd dir

     Sets the current directory.  Path names for other nicl commands may be relative to the cur-
     rent directory.

     Usage: pwd Prints the path of the current directory.

   auth (su)
     Usage: auth [user [password]]

     Authenticate as the named user, or as "root" if no user is specified.  If a password is sup-
     plied, then that password is used for authentication, otherwise the command prompts for a

   quit (q exit)
     Usage: quit Ends processing of interactive commands and terminates the program.

     Usage: refs Used with -x500 mode.	Lists parent domain and child domain references.  Domains
     are printed as LDAP URLS.

     Usage: setrdn path key

     Used with -x500 mode.  This command creates a meta-attribute "rdn" key in the specified
     directory, with the key as the value of the "rdn" meta-attribute.	When nicl is invoked with
     the -x500 flag, X.500-style naming is used.  The "rdn" meta-attribute of a directory speci-
     fies which key will be used for the relative distinguished name (RDN).  By default, the
     "name" property is used to form the RDN.
