Retrieving system and hardware information has never been easier. Information such as current kernel, VGA model and driver and even software repositories in use is now close at hand with inxi the command line system information script. Not only you can easily retrieve hardware information of your hard-drive, inxi also includes additional system information such as disk space used and block device file name. The most surprising and unexpected feature is retrieval of current local weather information, I'm not sure about usability of this feature but perhaps if your are worried about server overheating caused by outside whether temperature, inxi is your tool to avoid disaster.

inxi is very easy tool to use and does not need much usage explanation. In this article we review only some of the features offered by inxi just to simply illustrate the power of this tool. The full guide to inxi is available under --help option.

1. inxi Installation

inxi is currency available in a standard Ubuntu and Fedora repositories. At the time of writing inxi is not available in Debian linux. For Debian installation see: Installation of inxi system information script on Debian Wheezy
What follows are installation instructions for ubuntu and fedora linux:
UBUNTU:
$ sudo apt-get install inxi
FEDORA:
$ sudo yum install inxi

2. Quick system and hardware overview

inxi without any options prints a quick system overview.
$ inxi

3. Full system and hardware overview

Option -F allows for a full information about entire system:

4. Retrieving extra information

If additional data are available for any system or hardware component -xxx option will instruct inxi to display maximum possible information. For example here is a standrad information about network card(s):
$ inxi -N
Network:   Card-1: Intel 82579LM Gigabit Network Connection driver: e1000e
           Card-2: Intel Centrino Advanced-N 6205 [Taylor Peak] driver: iwlwifi
With -xxx option we are able to see additional information to the above output:
$ inxi -Nxxx
Network:   Card-1: Intel 82579LM Gigabit Network Connection
           driver: e1000e v: 2.3.2-k port: 4080 bus-ID: 00:19.0 chip-ID: 8086:1502
           Card-2: Intel Centrino Advanced-N 6205 [Taylor Peak]
           driver: iwlwifi v: in-tree:d bus-ID: 03:00.0 chip-ID: 8086:0085

5. Machine data, Motherboard and Bios Information

$ inxi -M
Machine:   System: LENOVO product: 4286CTO v: ThinkPad X220
           Mobo: LENOVO model: 4286CTO Bios: LENOVO v: 8DET61WW (1.31 ) date: 04/25/2012

6. Retrieving Repository information

$ inxi -r
Repos:     Active yum sources in file: /etc/yum.repos.d/google-chrome.repo
           google-chrome ~ http://dl.google.com/linux/chrome/rpm/stable/x86_64
           Active yum sources in file: /etc/yum.repos.d/rpmfusion-free-updates.repo
           rpmfusion-free-updates ~ http://mirrors.rpmfusion.org/mirrorlist?repo=free-fedora-updates-released-$releasever&arch=$basearch
           Active yum sources in file: /etc/yum.repos.d/rpmfusion-free.repo
           rpmfusion-free ~ http://mirrors.rpmfusion.org/mirrorlist?repo=free-fedora-$releasever&arch=$basearch
           Active yum sources in file: /etc/yum.repos.d/rpmfusion-nonfree-updates.repo
           rpmfusion-nonfree-updates ~ http://mirrors.rpmfusion.org/mirrorlist?repo=nonfree-fedora-updates-released-$releasever&arch=$basearch
           Active yum sources in file: /etc/yum.repos.d/rpmfusion-nonfree.repo
           rpmfusion-nonfree ~ http://mirrors.rpmfusion.org/mirrorlist?repo=nonfree-fedora-$releasever&arch=$basearch
           Active yum sources in file: /etc/yum.repos.d/virtualbox.repo
           virtualbox ~ http://download.virtualbox.org/virtualbox/rpm/fedora/$releasever/$basearch

7. Retrieving Weather Information

As it was already mentioned inxi is also able to provide current local weather information:
$ inxi -w
Weather:   Conditions: 53 F (12 C) - Clear Time: June 25, 11:05 AM CST
For other locations use -Woption followed by tzname location. For example:
$ inxi -W Bratislava,Slovakia
Weather:   Conditions: 54 F (12 C) - Clear Time: June 25, 4:11 AM CEST

8. Conclusion

The above are just few examples of inxi usage and the list would easily stretch to fill entire book. inxi is a powerful tool which should not be overlook. Linux system administration automation can be significant improved with inxi endless system and hardware information output.
