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

Synopsis

/usr/sbin/makedbm [-l] [-s] [-i yp_input_file] [-o yp_output_name]
[-d yp_domain_name] [-m yp_master_name] infile outfile

makedbm [-u dbmfilename]

Description

The makedbm command takes infile and converts it to a pair of files in dbm(3rpc) format named outfile.pag and outfile.dir. Each line of the input file is converted to a single dbm record.

Options

makedbm takes the following options:

-l: Lowercase. Convert the keys of the given map to lower case, so that host name matches, for example, can work independent of upper or lower case distinctions.
-s: Secure map. Accept connections from secure NIS networks only.
-i yp_input_file: Create a special entry with the key yp_input_file.
-o yp_output_name: Create a special entry with the key yp_output_name.
-d yp_domain_name: Create a special entry with the key yp_domain_name.
-m yp_master_name: 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 dbmfilename: Undo a dbm file. That is, print out a dbm file one entry per line, with a single space separating keys from values.

Usage

All characters up to the first <Tab> or <Space> form the key, and the rest of the line is the data. If a line ends with ``\'', then the data for that record is continued on to the next line. It is left for NIS clients to interpret ``#''; makedbm does not itself treat it as a comment character.

infile can be ``-'', in which case the standard input is read.

makedbm is meant to be used in generating dbm files for NIS and it generates a special entry with the key yp_last_modified, which is the date of infile (or the current time, if infile is ``-'').
