makedbm(8)                          CLIX                          makedbm(8)



  NAME

    makedbm - Makes an NIS dbm file

  SYNOPSIS

    /etc/yp/makedbm [-i yp-input-file] [-o yp-output-name] [-d yp-domain-name]
    [-m yp-master-name] infile outfile

    /etc/yp/makedbm [-u dbm-filename]

  FLAGS

    The following flags are recognized by makedbm:

    -i yp-input-file
           Creates a special entry with the key yp-input-file.

    -o yp-output-name
           Creates a special entry with the key yp-output-name.

    -d yp-domain-name
           Creates a special entry with the key yp-domain-name.

    -m yp-master-name
           Creates a special entry with the key yp-master-name.  If no master
           hostname is specified, yp-master-name is set to the local hostname.

    -u dbmfilename
           Undoes a dbm file.  That is, it displays a dbm file one entry per
           line, with a single space separating keys from values.

  DESCRIPTION

    The makedbm command converts infile to a pair of files in ndbm 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 ``\'', the data for that record is continued to the next line.  The
    clients of the Network Information Service (NIS) will interpret ``#'';
    makedbm does not treat it as a comment character.  The infile file can be
    -, in which case stdin is read.

    The makedbm command is used in generating dbm files for the NIS 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 -).

  EXAMPLES

    It is easy to write shell scripts to convert standard files such as
    /etc/passwd to the key value form used by makedbm.  For example, the awk

    command

    BEGIN { FS = ":"; OFS = "\t"; }
    { print $1, $0 }

    converts the /etc/passwd file to a form that can be read by makedbm to
    make the NIS passwd.byname file.  That is, the key is a username and the
    value is the remaining line in the /etc/passwd file.
