How to get your system information in Ubuntu

I stumbled upon the nifty “lshw” tool today. lshw lists your hardware. Try it now:
$sudo lshw

You can get specific details by using the -C flag:
$sudo lshw -C disk
will list all you hard disks.

It create an html page with your hardware details if you do a:
$sudo lshw -html > your-file-name.html
