MAKEDBM(1M)MAKEDBM(1M)NAMEmakedbm - make a dbm file, or get a text file from a dbm file
SYNOPSISmakedbm [-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 out‐
file.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_modi‐
fied, 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.
-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_mas‐
ter_name. If no master host name is speci‐
fied, yp_master_name is set to the local
host name.
-o yp_output_name
Create a special entry with the key yp_out‐
put_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 sin‐
gle space separating keys from values.
OPERANDS
The following operands are supported:
infile
Input file for makedbm. If infile is `−' (dash), the stan‐
dard input is read.
outfile
One of two output files in ndbm format: outfile.pag and out‐
file.dir.
