Name

makedbm

Synopsis

makedbm [options] infile outfile

Description

NFS/NIS command. Make NIS dbm file. makedbm takes infile and converts it 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 line ends with \&, the data for that record is continued on to the next line. It is left for the NIS clients to interpret #; makedbm does not treat it as a comment character. infile can be -, in which case the standard input is read.

makedbm generates a special entry with the key yp _last_modified, which is the date of infile (or the current time, if infile is -).
