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.
