dmidecode has even more useful switches:
- -s KEYWORD
- --string KEYWORD
- Only display the value of the DMI string identified by KEYWORD. [...]
- -t TYPE
- --type TYPE
- Only display the entries of type TYPE. TYPE can be either a DMI type number, or a comma-separated list of type numbers, or a keyword from the following list: bios, system, baseboard, chassis, processor, memory, cache, connector, slot. Refer to the DMI TYPES section below for details. [...]
- Do not decode the entries, dump their contents as hexadecimal instead. [...]
- --dump-bin FILE
- Do not decode the entries, instead dump the DMI data to a file in binary form. [...]
You could use -s and -t to filter inside dmidecode, so that you have less data to process.
The -u switch generates a slightly more predictable format. You could decode the hexdumps inside perl, using knowledge from DMI::Decode (i.e. copy and port the C code from there to perl).
The --dump-bin switch delivers the raw DMI data, which you could decode all by yourself, again by using knowledge from DMI::Decode.
Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)
