dev_mkdb -- create /dev database
dev_mkdb [-o database] [directory]
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:
Put the output databases in the named file.
/dev Device directory.
/var/run/dev.db Database file.
ps(1), stat(2), db(3), devname(3), kvm_nlist(3), ttyname(3), kvm_mkdb(8)
The dev_mkdb command appeared in 4.4BSD.
