dminfo reports and updates information about the device_maps(5) file.


The following options are supported

Succeed if any of the requested entries are found. If
used with -v, all entries that match the requested
case(s) are printed.

-d dev-path
Search by dev-path. Search device_maps(5) for a device
special pathname in the device_list field matching the
dev-path argument. This option cannot be used with -n,
-t or -u.

-f pathname
Use a device_maps file with pathname instead of

-n dev-name
Search by dev-name. Search device_maps(5) for a
device_name field matching dev-name. This option cannot
be used with -d, -t or -u.

-t dev-type
Search by dev-type. Search device_maps(5) for a
device_type field matching the given dev-type. This
option cannot be used with -d, -n or -u.

-u dm-entry
Update the device_maps(5) file. This option is provided
to add entries to the device_maps(5) file. The dm-entry
must be a complete device_maps(5) file entry. The
dm-entry has fields, as in the device_maps file. It
uses the colon (:) as a field separator, and white
space as the device_list subfield separators. The
dm-entry is not made if any fields are missing, or if
the dm-entry would be a duplicate. The default device
maps file can be updated only by the super user.

Verbose. Print the requested entry or entries, one line
per entry, on the standard output. If no entries are
specified, all are printed.
