makedbm - make a dbm file, or get a text file from a dbm
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 ndbm(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.
Create a special entry with the key yp_domain_name.
-D number_of delimiters
Specify number_of_delimiters to skip before forming
-E Delimiters are escaped.
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.
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.
Create a special entry with the key yp_output_name.
-s Secure map. Accept connections from secure NIS net-
Specify the delimiter to use instead of the default
delimiter for forming the key.
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:
Input file for makedbm. If infile is `-' (dash), the
standard input is read.
One of two output files in ndbm format: outfile.pag
