Name
       makedbm - make a yellow pages dbm file

Syntax
       makedbm [ -i yp_input_file ] [ -o yp_output_name ] [ -d yp_domain_name ] [ -m yp_master_name ] infile outfile
       makedbm [ -u dbmfilename ]

Description
       The command takes the file specified by the argument infile and converts it to a pair of files in format, namely and Each line of the input
       file is converted to a single record.  All characters up to the first tab or space form the key, and the rest of the line is defined as the
       key's  associated data.	If a line ends with a backslash (), the data for that record is continued onto the next line.	It is left for the
       clients of the yellow pages to interpret the number sign (#); does not treat it as a comment character.	The  infile  parameter	can  be  a
       hyphen (-), in which case reads the standard input.

       The  command  is  meant	to  be	used in generating files for the yellow pages service.	The command generates a special entry with the key
       yp_last_modified, which is the date of infile.

Options
       -i     Create a special entry with the key yp_input_file.

       -o     Create a special entry with the key yp_output_name.

       -d     Create a special entry with the key yp_domain_name.

       -m     Create a special entry with the key yp_master_name.  If no master host name is specified, yp_master_name will be set  to	the  local
	      host name.

       -u     Undo a file.  That is, print out a file one entry per line, with a single space separating keys from values.

Examples
       The  following  example shows how a combination of commands can be used to make the yellow pages files and from the file.  The percent sign
       (%) signifies the system prompt.

       % awk 'BEGIN { FS = ":"; OFS = ""; }
	{ print $1, $0 }' /etc/passwd > ptmp
       % makedbm ptmp passwd.byname
       % rm ptmp

       The command creates the file ptmp which is in a form usable by The command uses the ptmp file to create the yellow pages dbm files and  The
       command removes the ptmp file.

NAME

       makedbm - Makes a Network Information Service (NIS) dbm file

SYNOPSIS

       /var/yp/makedbm	[-i yp_input_file] [-s yp_secure_name] [-a method] [-o yp_output_name] [-d yp_domain_name] [-m yp_master_name] infile out-
       file

       /var/yp/makedbm [-u dbmfilename]

OPTIONS

       Specifies that NIS maps are to be stored in one of the following formats: btree -- Recommended when creating  and  maintaining  very  large
       maps.   dbm/ndbm  -- For backward compatibility.  This is the default.  hash -- A potentially quicker method for managing small maps.  Cre-
       ates a special entry with the key yp_input_file.  Creates a special entry with the key yp_secure_file. This causes the makedbm  command	to
       write  a  secure map.  The key value ypserver looks for YP_SECURE.  Creates a special entry with the key yp_output_name.  Creates a special
       entry with the key yp_domain_name.  Creates a special entry with the key yp_master_name. If no  master  host  name  is  specified,  yp_mas-
       ter_name  will  be  set	to the local host name.  Undoes a dbm file. That is, prints out a dbm file one entry per line, with a single space
       separating keys from values.

DESCRIPTION

       The makedbm command takes the file specified by the argument infile and converts it to a  single  file  or  a  pair  of	files  in  dbm(3),
       btree(3),  or  hash(3)  format. The dbm(3) files are stored as outfile.pag and outfile.dir. The btree(3) files are stored as outfile.btree.
       Each line of the input file is converted to a single dbm record. All characters up to the first tab or space form the key, and the rest	of
       the  line is defined as the key's associated data. If a line ends with a backslash (), the data for that record is continued onto the next
       line. It is left for the Network Information Service (NIS) clients to interpret the number sign (#); makedbm does not treat it as a comment
       character.  The infile parameter can be a hyphen (-), in which case makedbm reads the standard input.

       The  makedbm  command  is meant to be used in generating database files for NIS. The makedbm command generates a special entry with the key
       yp_last_modified, which is the date of infile.

RESTRICTIONS

       You must use the same database format for each map in a domain. In addition, a server serving multiple NIS domains must use the same  data-
       base format for all domains.

       Although  a  Tru64  UNIX  NIS server that takes advantage of btree files will be able to store very large maps, NIS slave servers that lack
       this feature might have a much smaller limit on the number of map entries they can handle.  It may not be possible to distribute very large
       maps  from  a Tru64 UNIX NIS master server to a slave server that lacks support for very large maps.  NIS clients are not affected by these
       enhancements.

EXAMPLES

       The following example shows how a combination of commands can be used to make the NIS dbm  files  passwd.byname.pag  and  passwd.byname.dir
       from the /etc/passwd file.  The percent sign (%) signifies the system prompt.  % awk 'BEGIN { FS = ":"; OFS = "	"; }
	{ print $1, $0 }' /etc/passwd > ptmp % makedbm ptmp passwd.byname % rm ptmp

	      The  awk	command  creates  the file ptmp which is in a form usable by makedbm. The makedbm command uses the ptmp file to create the
	      database files. The rm command removes the ptmp file.  The following is an example of the makedb command used with the btree  format
	      database routine to store NIS maps.  makedbm -a b ...
