GNU/Linux Command – DMIDECODE

dmidecode — DMI Table Decoder

dmidecode is a tool for dumping a computer’s DMI or SMBIOS table contents in a human-readable format. This table contains a detailed description of the system’s hardware components. It is very helpful to retrieve the device information without probing the actual hardware. SMBIOS stands for System Management BIOS, while DMI stands for Desktop Management Interface. Both standards are tightly related and developed by the DMTF (Desktop Management Task Force). The records in DMI table will have the following fields: Handle, Type, Size, Value.

Examples: $ dmidecode -- Error. Need super user permission. # dmidecode -- Dump the whole table on the screen. # dmidecode -q -- Show Active and standard values only. # dmidecode -s bios-vendor -- Show the value for the KEYWORD. # dmidecode -t bios -- Show entries belong to this TYPE. # dmidecode -u -- Dump the table in hex format.
