Hi

In this post you can see some useful command to find and show hardware information on Linux.

Default commands

ALL devices

dmesg

dmesg will show you the kernel messages which can show you all the devices the kernel has found (hard disks,cdroms,etc)

CPU

# cat /proc/cpuinfo

Memory

# cat /proc/meminfo
$ free

PCI (including usb bridges,agp cards etc)

$ lspci

USB devices (mice,etc)

$ lsusb

Hard drives

# fdisk -l
$ df -h

Additional Command

lshw

lshw is a Linux command which provides details of all the hardware in your PC. The details provided by the lshw command run the gamut of processors, memory, slots, onboard sound, video chipset and more.

Install lshw

Arch:

# pacman -S lshw

Debain, Ubuntu or any of its derivatives:

$ sudo aptitude install lshw

Redhat, fedora, CentOS:

# yum install lshw

Gentoo:

# emerge lshw

Run lshw

# lshw
# lshw -short

To get the output in HTML, you use the -html option as follows:

# lshw -html > hardware-info.html

• See lshw command – List hardware information in Linux

dmidecode

dmidecode command reads the system DMI table to display hardware and BIOS information of the server. Apart from getting current configuration of the system, you can also get information about maximum supported configuration of the system using dmidecode. For example, dmidecode gives both the current RAM on the system and the maximum RAM supported by the system.
dmidecode is installed by default on many linux distribution like debain, ubuntu and fedora.

Hi

Identi.ca is an open source social networking and micro-blogging service.
I like Ideni.ca. It’s good service.

I use CLI (command line) everyday. I like to dented from it. It’s simple.
Just install cURL:

$ sudo apt-get install curl

And type:

$ curl -u username:password -d status="message" http://identi.ca/api/statuses/update.xml

You will receive a response containing the XML coding for your post which acts as a confirmation that your post was submitted.

Also you can create a shell file for this
Open a new text document and add the following, save it as identica.sh (or anything ending in sh):

#!/bin/bash
curl -u username:password -d status=″$1" http://identi.ca/api/statuses/update.xml

Make sure you change the chmod to 777 using the following command.

$ chmod 777 /path/to/file/

When you located the file (or add a bash prompt) it makes it simplier to identi.ca the rules. For example you can type the following to command to link to the file.

$ ./path/to/idetica.sh "Message"
