MAKEDBM(8) Maintenance Commands and Procedures MAKEDBM(8)

NAME

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

SYNOPSIS

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]

DESCRIPTION

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.

OPTIONS

The following options are supported:

-b
Insert the YP_INTERDOMAIN into the
output. This key causes ypserv(8) 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
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 networks 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.

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.
