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

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.
