NAME

makedbm − make a dbm file, or get a text file from a 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 ndbm(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 ‘ \ ’ (backslash), the data for that record is continued on to the next line.  makedbm does not treat ‘ # ’ (pound-sign) as a special character.  infile can be ‘ − ’ (dash), in which case the standard input is read. 

makedbm is mainly used in generating dbm files for the NIS name service, and, to that end, 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

−l Lower case.  Convert the keys of the given map to lower case, so that, for example, host name matches will succeed independent of upper or lower case distinctions. 

−s Secure map.  Accept connections from secure NIS 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; i.e., print out the file in text format, one entry per line, with a single space separating keys from values.
