makedbm [ -u dbmfilename ]

Description

The makedbm command takes infile and converts it to a pair of files in ndbm(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 ‘ \ ’ (backslash), the data for that record is continued on to the next line. makedbm does not treat ‘ # ’ (pound-sign) as a special character. infile can be ‘ - ’ (dash), in which case the standard input is read.

makedbm is mainly used in generating dbm files for the NIS name service, and, to that end, 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

-b

Insert the YP_INTERDOMAIN into the output. This key causes ypserv to use DNS for host name and address lookups for hosts not found in the maps.

-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.

-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; i.e., print out the file in text format, one entry per line, with a single space separating keys from values.
