DEV_MKDB(8)               BSD System Manager's Manual              DEV_MKDB(8)

NAME
     dev_mkdb -- create /dev database

SYNOPSIS
     dev_mkdb [-o database] [directory]

DESCRIPTION
     The dev_mkdb command creates a db(3) hash access method database in
     ``/var/run/dev.db'' which contains the names of all of the character and
     block special files in the specified directory, using the file type and
     the st_rdev field as the key.  If no directory is specified, the ``/dev''
     directory is used.

     Keys are a structure containing a mode_t followed by a dev_t, with any
     padding zero'd out.  The former is the type of the file (st_mode &
     S_IFMT), the latter is the st_rdev field.

     The options are as follows:

     -o database
             Put the output databases in the named file.

FILES
     /dev             Device directory.
     /var/run/dev.db  Database file.
