NAME

makedbm - make a YP dbm file

SYNOPSIS

/usr/sbin/makedbm   [-l]   [-s]   [-i   yp_input_file]   [-o
yp_output_name]
     [-d yp_domain_name] [-m yp_master_name] infile  outfile
makedbm [-u dbmfilename]

DESCRIPTION

The makedbm command takes infile and converts it to a pair of files in dbm(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 `\', then the data for that record is continued on to the next line. It is left for the clients of the YP name service to interpret `#'; makedbm does not itself treat it as a comment character. infile can be `-', in which case the standard input is read. makedbm is meant to be used in generating dbm files for the YP name service, and 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 following options are available:

-l Lowercase. Convert the keys of the given map to lower case, so that host name matches, for example, can work independent of upper or lower case distinctions.

-s Secure map. Accept connections from secure YP 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. That is, print out a dbm file one entry per line, with a single space separating keys from values.
