makedbm
makedbm(8yp)makedbm(8yp)Name
makedbm - make a yellow pages dbm file
Syntax
makedbm [ -i yp_input_file ] [ -o yp_output_name ] [ -d yp_domain_name ] [ -m yp_master_name ] infile outfile
makedbm [ -u dbmfilename ]
Description
The command takes the file specified by the argument infile and converts it to a pair of files in format, namely and Each line of the input
file is converted to a single record. All characters up to the first tab or space form the key, and the rest of the line is defined as the
key's associated data. If a line ends with a backslash (), the data for that record is continued onto the next line. It is left for the
clients of the yellow pages to interpret the number sign (#); does not treat it as a comment character. The infile parameter can be a
hyphen (-), in which case reads the standard input.
The command is meant to be used in generating files for the yellow pages service. The command generates a special entry with the key
yp_last_modified, which is the date of infile.
Options-i Create a special entry with the key yp_input_file.
-o Create a special entry with the key yp_output_name.
-d Create a special entry with the key yp_domain_name.
-m 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 Undo a file. That is, print out a file one entry per line, with a single space separating keys from values.
Examples
The following example shows how a combination of commands can be used to make the yellow pages files and from the file. The percent sign
(%) signifies the system prompt.
% awk 'BEGIN { FS = ":"; OFS = ""; }
{ print $1, $0 }' /etc/passwd > ptmp
% makedbm ptmp passwd.byname
% rm ptmp
The command creates the file ptmp which is in a form usable by The command uses the ptmp file to create the yellow pages dbm files and The
command removes the ptmp file.
