SYNOPSISdev_mkdb [-f file] [directory]
DESCRIPTION
The dev_mkdb utility creates a db(3) hash access method database in file
(/var/run/dev.db by default) which contains the names of all of the char‐
acter and block special files in directory (/dev by default), using the
file type and the st_rdev field as the key.
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.
