  • dmidecode - full system info for Linux

    I've been using Linux for many years - back to when it was a hobby OS and the 0.x kernel was out. Even so, I'm always learning new things from the people around me -- much like with OTM / G-Log. Today's lesson came from a friend of mine, Ralph:

    Not sure if either of you have com across this yet or not, but if you
    have not, it is quite impressive. I did try this on other unix flavors
    but it seems to be only on Linux.

    Type "dmidecode" at a linux prompt and it will list out all
    specifications of a linux machine.
    System Manufacturer
    Bios Level
    Bios Settings
    Hardware information such as
    - Memory modules
    - Processors
    - PCI Cards
    - System Cache
    And much much more. Pretty impressive.

    Here's some real-world output from dmidecode -- as you can tell, it's definitely very detailed and helpful for us sysadmins!
