makedbm - make a dbm file, or get a text file from a dbm file


makedbm [ -b ] [ -l ] [ -s ] [ -E ] [ -i yp_input_file ] [ -o yp_output_name ] [ -d yp_domain_name ] [ -m yp_master_name ] [ -S delimiter ] [ -D number_of_delimiters ] infile outfile makedbm [ -u dbmfilename ]


The makedbm utility takes the infile and converts it to a pair of files in ndbm format (see dbm_clearerr(3C)), 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.


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. -D number_of delimiters Specify number_of_delimiters to skip before forming the key. -E Delimiters are escaped. -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 succeed independent of upper or lower case distinctions. -m yp_master_name SunOS 5.8 Last change: 17 Aug 1999 1 Maintenance Commands makedbm(1M) Create a special entry with the key yp_master_name. If no master host name is specified, yp_master_name is 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 net- works only. -S delimiter Specify the delimiter to use instead of the default delimiter for forming the key. -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.


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.
