NAME

     dev_mkdb -- create /dev database

SYNOPSIS

     dev_mkdb [-c] [-o database] [directory]

DESCRIPTION

     The dev_mkdb command creates a cdbr(3) database in ``/var/run/dev.cdb'' 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:

     -c      Create a db(3) database for compatibility with libc versions and statically linked programs from before NetBSD 6.0.  The default name
	     is ``/var/run/dev.db''.

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

FILES

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