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.
