-- Command: smbios [--type TYPE] [--handle HANDLE] [--match MATCH]
(--get-byte | --get-word | --get-dword | --get-qword |
--get-string | --get-uuid) OFFSET [--set VARIABLE]
Retrieve SMBIOS information.
The 'smbios' command returns the value of a field in an SMBIOS
structure. The following options determine which structure to
select.
* Specifying '--type' will select structures with a matching
TYPE. The type can be any integer from 0 to 255.
* Specifying '--handle' will select structures with a matching
HANDLE. The handle can be any integer from 0 to 65535.
* Specifying '--match' will select structure number MATCH in the
filtered list of structures; e.g. 'smbios --type 4 --match 2'
will select the second Process Information (Type 4) structure.
The list is always ordered the same as the hardware's SMBIOS
table. The match number must be a positive integer. If
unspecified, the first matching structure will be selected.
The remaining options determine which field in the selected SMBIOS
structure to return. Only one of these options may be specified at
a time.
* When given '--get-byte', return the value of the byte at
OFFSET bytes into the selected SMBIOS structure. It will be
formatted as an unsigned decimal integer.
* When given '--get-word', return the value of the word (two
bytes) at OFFSET bytes into the selected SMBIOS structure. It
will be formatted as an unsigned decimal integer.
* When given '--get-dword', return the value of the dword (four
bytes) at OFFSET bytes into the selected SMBIOS structure. It
will be formatted as an unsigned decimal integer.
* When given '--get-qword', return the value of the qword (eight
bytes) at OFFSET bytes into the selected SMBIOS structure. It
will be formatted as an unsigned decimal integer.
* When given '--get-string', return the string with its index
found at OFFSET bytes into the selected SMBIOS structure.
* When given '--get-uuid', return the value of the UUID (sixteen
bytes) at OFFSET bytes into the selected SMBIOS structure. It
will be formatted as lower-case hyphenated hexadecimal digits,
with the first three fields as little-endian, and the rest
printed byte-by-byte.
The default action is to print the value of the requested field to
the console, but a variable name can be specified with '--set' to
store the value instead of printing it.
For example, this will store and then display the system
manufacturer's name.
smbios --type 1 --get-string 4 --set system_manufacturer
echo $system_manufacturer
