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 num-
       ber_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_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  inde-
                               pendent 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.
