infile outfilemakedbm [
NFS/NIS command. Create or dump an NIS dbm file. makedbm will take a text infile and convert it to a gdbm database file named outfile. This file is suitable for use with ypserv. 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 the data. If a line ends with \&, the data for that record is continued onto the next line. The # character is given no special treatment. infile can be -, in which case the standard input is read.
makedbm generates two special keys: the YP_M*ER_NAME key, which is the value of the current host (unless another name is specified with -m), and the YP_L*_MODIFIED key, which is the date of infile (or the current time if infile is -).
Add support for mail aliases.
Insert YP_INTERDOMAIN key into map. This indicates that ypserv should fall back to DNS lookups when a host’s address is not found in NIS.
Send a YPPROC_CLEAR signal to ypserv, causing it to clear all cached entries.
Create a YP_INPUT_NAME key with the value file_name.
Convert keys of the given map to lowercase.
Specify the value of the YP_M*ER_NAME key. The default value is the current hostname.
Don’t enforce NIS size limits for keys or data.
Create a YP_OUTPUT_NAME key with the value file_name.
Treat lines beginning with # as comments. Do not include them in the datafile.
