DESCRIPTION
The
dev_mkdb command creates a
db(3) hash access method database in “
/var/run/dev.db” 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:
-
-o database
-
Put the output databases in the named file.
