makedbm(1M) — ADMINISTRATOR COMMANDS
NAME
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(3) format, namely outfile.pag and outfile.dir. 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 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 ‘−’).
The following options are available:
−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.
