       nistbladm - NIS+ table administration command

       nistbladm -a | -A [-D defaults] colname = value... tablename

       nistbladm -a | -A [-D defaults] indexedname

       nistbladm -c [-D defaults] [-p path] [-s sep] type colname =
	    [flags] [, access]... tablename

       nistbladm -d tablename

       nistbladm -e | -E colname = value... indexedname

       nistbladm -m colname = value... indexedname

       nistbladm -r | -R [colname = value...] tablename

       nistbladm -r | -R indexedname

       nistbladm -u [-p path] [-s sep] [-t type]
	    [colname = access...] tablename

       The  nistbladm  command	is used to administer  NIS+ tables. There are five primary opera-
       tions that it performs: creating and deleting tables, adding entries to, modifying entries
       within, and removing entries from tables.

       Though NIS+ does not place restrictions on the size of tables or entries, the size of data
       has an impact on the performance and the disk space requirements of the NIS+ server.  NIS+
       is  not	designed  to store huge pieces of data, such as files; instead, pointers to files
       should be stored in NIS+.

       NIS+ design is optimized to support 10,000 objects with a total size of 10M bytes. If  the
       requirements  exceed  the  above, it is suggested that the domain hierarchy be created, or
       the data stored in the tables be pointers to the actual data, instead of the data itself.

       When creating tables, a table type, type, and a list of column definitions  must  be  pro-

       type  is a string that is stored in the table and later used by the service to verify that
       entries being added to it are of the correct type.

       Syntax for column definitions is:


       flags is a combination of:

       S    Searchable. Specifies that searches can be done on	the  column's  values  (see  nis-

       I    Case-insensitive  (only  makes  sense in combination with S). Specifies that searches
	    should ignore case.

       C    Crypt. Specifies that the column's values should be encrypted.

       B    Binary data (does not make sense in combination with S). If  not  set,  the  column's
	    values are expected to be null terminated ASCII strings.

       X    XDR encoded data (only makes sense in combination with B).

       access is specified in the format as defined by the nischmod(1) command.

       When  manipulating  entries, this command takes two forms of entry name.  The first uses a
       series of space separated  colname=value pairs that specify column values  in  the  entry.
       The second is a NIS+ indexed name, indexedname, of the form:

	 [ colname=value, ... ],tablename

       The following options are supported:

       -a | A	       Adds entries to a NIS+ table. The difference between the lowercase `a' and
		       the uppercase `A' is in the treatment of preexisting entries. The  entry's
		       contents  are  specified  by  the  column=value pairs on the command line.
		       Values for all columns must be specified when adding entries to a table.

		       Normally, NIS+ reports an error if an attempt is made to add an entry to a
		       table  that  would  overwrite  an entry that already exists. This prevents
		       multiple parties from adding duplicate entries and having one of them  get
		       overwritten.  If  you  wish  to force the add, the uppercase `A' specifies
		       that the entry is to be added, even if it already exists. This  is  analo-
		       gous to a modify  operation on the entry.

       -c	       Creates	a  table named tablename in the namespace. The table that is cre-
		       ated must have at least one column and at least one column must be search-

       -d tablename    Destroys the table named tablename. The table that is being destroyed must
		       be empty. The table's contents can be deleted with the -R option below.

       -e|E	       Edits the entry in the table that is specified by  indexdname.  indexdname
		       must uniquely identify a single entry. It is possible to edit the value in
		       a column that would change the indexed name of an entry.

		       The change (colname=value) may affect other entries in the  table  if  the
		       change  results	in an entry whose indexed name is different from indexed-
		       name and which matches that of another existing entry. In this  case,  the
		       -e  option  will  fail  and  an error will be reported. The -E option will
		       force the replacement of the existing entry by the new entry  (effectively
		       removing two old entries and adding a new one).

       -m	       A synonym for -E. This option has been superseded by the -E option.

       -r|R	       Removes	entries  from a table. The xentry is specified by either a series
		       of  column=value pairs on the command line, or an  indexed  name  that  is
		       specified  as  entryname. The difference between the interpretation of the
		       lowercase `r' versus the uppercase `R' is in the treatment  of  non-unique
		       entry specifications. Normally the NIS+ server will disallow an attempt to
		       remove an entry	when  the  search  criterion  specified  for  that  entry
		       resolves  to  more  than one entry in  the table. However, it is sometimes
		       desirable to remove more than one entry, as when  you  are  attempting  to
		       remove  all of the entries from a table. In this case, using the uppercase
		       `R' will force the NIS+ server to remove all entries matching  the  passed
		       search  criterion.  If  that criterion is null and no column values speci-
		       fied, then all entries in the table will be removed.

       -u	       Updates attributes of a table. This allows the  concatenation  path  (-p),
		       separation  character (specified with the (-s)), column access rights, and
		       table type string (-t) of a table to be changed.  Neither  the  number  of
		       columns, nor the columns that are searchable may be changed.

       -D defaults     When  creating  objects, this option specifies a different set of defaults
		       to be used during this operation. The  defaults	string	is  a  series  of
		       tokens  separated  by colons. These tokens represent the default values to
		       be used for the generic object properties. All of  the  legal  tokens  are
		       described below.

		       ttl=time 	  This	token  sets  the default time to live for objects
					  that are created by this command.  The  value  time  is
					  specified  in  the format as defined by the nischttl(1)
					  command. The default value is 12 hours.

		       owner=ownername	  This token specifies that the NIS+ principal	ownername
					  should  own  the created object. Normally this value is
					  the same as the principal who is executing the command.

		       group=groupname	  This token specifies that the group groupname should be
					  the  group  owner  for the object that is created.  The
					  default value is NULL.

		       access=rights	  This token specifies the set of access rights that  are
					  to be granted for the given object. The value rights is
					  specified in the format as defined by the   nischmod(1)
					  command. The default value is ----rmcdr---r---.

       -p path	       When  creating  or  updating  a	table,	this option specifies the table's
		       search path. When a  nis_list() function is invoked, the user can  specify
		       the  flag   FOLLOW_PATH	to  tell the client library to continue searching
		       tables in the table's path if the search criteria used does not yield  any
		       entries. The path consists of an ordered list of table names, separated by
		       colons. The names in the path must be fully qualified.

       -s  sep	       When creating or updating a table, this option specifies the table's sepa-
		       rator  character.  The separator character is used by  niscat(1) when dis-
		       playing tables on the standard output. Its purpose is to  separate  column
		       data when the table is in ASCII form. The default value is a space.

       -t type	       When updating a table, this option specifies the table's type string.

       Example 1 Creating an Unmodifiable Table

       This  example  creates  a  table  named	hobbies  in  the  directory  foo.com. of the type
       hobby_tbl with two searchable columns,  name and  hobby.

	 example% nistbladm -c hobby_tbl name=S,\
	       a+r,o+m hobby=S,a+r hobbies.foo.com.

       The column name has read access for all (that is,  owner, group,  and  world)  and  modify
       access for only the owner. The column hobby is readable by all, but not modifiable by any-

       In this example, if the access rights had not been specified, the  table's  access  rights
       would  have  come  from	either	the  standard defaults or the  NIS_DEFAULTS variable (see

       Example 2 Adding Entries to the Table

       To add entries to this table:

	 example% nistbladm -a name=bob hobby=skiing hobbies.foo.com.
	 example% nistbladm -a name=sue hobby=skiing hobbies.foo.com.
	 example% nistbladm -a name=ted hobby=swimming hobbies.foo.com.

       Example 3 Adding the Concatenation Path

       In the following example, the common root domain is foo.com (NIS+ requires  at  least  two
       components  to  define  the root domain) and the concatenation path for the subdomains bar
       and baz are added:

	 example% nistbladm -u -p hobbies.bar.foo.com.:hobbies.baz.foo.com. \

       Example 4 Deleting Skiers from the List

       To delete the skiers from our list:

	 example% nistbladm -R hobby=skiing hobbies.foo.com.

       Note:  The use of the  -r option would fail because there are two entries with  the  value
       of skiing.

       Example 5 Naming a Column with no Flags Set

       To  create a table with a column that is named with no flags set, you supply only the name
       and the equals (=) sign as follows:

	 example% nistbladm -c notes_tbl name=S,a+r,o+m note=  notes.foo.com.

       This example created a table, named notes.foo.com., of type  notes_tbl  with  two  columns
       name and note. The note column is not searchable.

       Example 6 Protecting Terminal Characters

       When  entering data for columns in the form of a value string, it is essential that termi-
       nal characters be protected by single or double quotes. These are  the  characters  equals
       (=),  comma  (,), left bracket ([), right bracket (]), and space ( ). These characters are
       parsed by NIS+ within an indexed name. These characters are  protected  by  enclosing  the
       entire value in double quote (") characters as follows:

	 example% nistbladm -a fullname="Joe User" nickname=Joe nicknames

       If  there  is any doubt about how the string will be parsed, it is better to enclose it in

       NIS_DEFAULTS    This variable contains a defaults string that will be override  the   NIS+
		       standard  defaults. If the  -D switch is used those values will then over-
		       ride both the  NIS_DEFAULTS variable and the standard defaults.

       NIS_PATH        If this variable is set, and the NIS+ table name is not	fully  qualified,
		       each  directory	specified  will be searched until the table is found. See

       The following exit values are returned:

       0    Successful operation.

       1    Operation failed.

       See attributes(5) for descriptions of the following attributes:

       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |Availability		     |SUNWnisu			   |

       NIS+(1), niscat(1), nischmod(1), nischown(1),  nischttl(1),  nisdefaults(1),  nismatch(1),
       nissetup(1M), attributes(5)

       NIS+  might  not be supported in future releases of the Solaris operating system. Tools to
       aid the migration from NIS+ to LDAP are available in the current Solaris release. For more
       information, visit http://www.sun.com/directory/nisplus/transition.html.

       To modify one of the entries, say, for example, from "bob" to "robert":

	 example% nistbladm -m name=robert [name=bob],hobbies

       Notice  that  "[name=bob],hobbies"  is  an indexed name, and that the characters `[' (open
       bracket) and `]' (close bracket) are interpreted by the shell. When typing entry names  in
       the form of  NIS+ indexed names, the name must be protected by using single quotes.

       It  is possible to specify a set of defaults such that you cannot read or modify the table
       object later.
