.Sh DESCRIPTION
|
||||
The

utility creates a

.Xr db 3
|
||||
hash access method database in
|
||||
.Ar file
|
||||
.Pa ( /var/run/dev.db
|
||||
by default)
|

which contains the names of all of the character and block special
|
||||
files in
|
||||
.Ar directory
|
||||
.Pa ( /dev
|
||||
by default), using the file type and the
|
||||
.Fa st_rdev
|
||||
field as the key.
|
||||
.Pp
|
||||
Keys are a structure containing a

||||
.Vt mode_t
|
||||
followed by a
|
||||
.Vt dev_t ,
|

The former is the type of the file
|
||||
.Va ( st_mode Li & Dv S_IFMT ) ,
