inxi

inxi is a script that shows system information.  For info on inxi and smxi, see:
http://smxi.org/site/install.htm#inxi
http://smxi.org/site/install.

Here's how I installed it in PCLinuxOS:

# cd /usr/bin
# wget -Nc smxi.org/inxi && chmod +x inxi && inxi

The last "inxi" runs the script.

inxi -h gives you a list of options.  inxi -CFfpluorsic10 -t cm10 shows just about everything, but inxi -xrFA is a pretty good one to run:
