makedbm(1M)
NAME
makedbm − make a dbm file, or get a text file from a dbm file
SYNOPSIS
makedbm [ B −bls ] [ −d yp_domain_name ] [ −i yp_input_file ]
[ −o yp_output_name ] [ −m yp_master_name ] infile outfile
makedbm [−u dbmfilename ]
DESCRIPTION
The makedbm utility takes the infile and converts it to a pair of files in ndbm format (see dbm_clearerr(3)), 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 ‘\’ (backslash), the data for that record is continued on to the next line. makedbm does not treat ‘#’ (pound-sign) as a special character.
Because makedbm is mainly used in generating dbm files for the NIS name service, 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 entries that have keys with the prefix yp_ are interpreted by NIS server utilities.
OPTIONS
The following options are supported:
−b Insert the YP_INTERDOMAIN into the output. This key causes ypserv(1M) to use DNS for host name and address lookups for hosts not found in the maps.
−d yp_domain_name
Create a special entry with the key yp_domain_name.
−i yp_input_file Create a special entry with the key yp_input_file.
−l Lower case. Convert the keys of the given map to lower case, so that, for example, host name matches will succeed independent of upper or lower case distinctions.
−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.
−o yp_output_name Create a special entry with the key yp_output_name.
−s Secure map. Accept connections from secure NIS networks only.
−u dbmfilename Undo a dbm file. Prints out the file in text format, one entry per line, with a single space separating keys from values.
OPERANDS
The following operands are supported:
infile Input file for makedbm. If infile is ‘−’ (dash), the standard input is read.
outfile One of two output files in ndbm format: outfile&.pag and outfile&.dir.
