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:
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”.
Put the output databases in the named file.
