Troubleshooting, upgrading, or just curious? Find out what’s in your system
 without opening the case. Using these Linux command line tools, you can get
 details about your hardware and distribution.

I’ve tested these commands in Ubuntu 7.10, but they should all work in othe
r Linux distributions. Unless noted otherwise, all of this software is inclu
ded by default with Ubuntu.

Graphics card:

glxinfo - details about OpenGL, the Xserver, and your graphics card

glxinfo | grep direct - do you have direct 3d rendering?

glxinfo | grep vendor - graphics card vendor

lspci | grep VGA - specific graphics card model

glxgears - a simple 3d benchmark, prints frame rate to the terminal

xrandr - supported display resolutions

Audio:

lspci | grep Audio - audio controller

aplay --list-devices - more audio device information

Software versions:

cat /etc/issue - current distribution and version

apt-cache showpkg packagename - packagename’s version and dependencies

uname -r - Linux kernel version

uname -a - all kernel details

Networking:

lspci | grep Ethernet - Ethernet controllers

ifconfig - networking interfaces, IP addresses, and more

Processor:

cat /proc/cpuinfo - all processors, clock speeds, flags, and more

cat /proc/loadavg - processor load average for the last 1, 5, and 15 minutes


top - press C key to sort processes by CPU usage

Memory:

cat /proc/meminfo - amount of RAM and swap, and how much is being used for w
hat

free -m - total, used, and free memory shown in MB

top - press M key to sort processes by memory usage

Hard disks:

df -H - partitions, as well as their mount-points and usage in GB

sudo fdisk -l - all partitions, their device names, and positions on disk

USB devices:

lsusb - USB buses and attached devices

Even more:

lshal -m - monitor for hardware changes

lspci - all PCI devices

hwinfo --short (install from package hwinfo) - overview of all hardware, as
well as more detailed info

lshw - another program for listing hardware

lshw -html | w3m -T text/html - lists hardware with HTML output in the w3m w
eb browser

uptime - current time elapsed since last reboot, users, and load average

Did I forget anything? Leave a comment below if you have something to add.
