In this How To i will show you how to check your temperatures in Linux. This works on all Debian based Linux distros. You will need to install two packages to read your temps. These are: lm-sensors and hddtemp. To install them type this into a terminal:
sudo apt-get install lm-sensors hddtemp
And type in your password when prompted. Once they've installed run this command:
sudo sensors-detect
and type in you password when prompted. This command scans your computer for any sensors it can find. It will ask you whether you want to scan for different types of sensors. Say yes to all these questions. When it's done it will show a list of drivers that are needed for the sensors that it finds. It will ask if you want to add these drivers to your "/etc/modules" file. Say yes here. Now when you type in this command:
sudo sensors
And type in your password when prompted. It should display the temperatures of all the sensors it found as well as any fan speed sensors.
To use hddtemp just simply run this command (and type in your password when prompted.) and it should display the temperature of your hard disk:
sudo hddtemp /dev/sda
Note: This part "/dev/sda" might be different on your computer. If "sda" doesn't work try "hda". Also if you have multiple hard drives then to check you second one replace "sda" with "sdb". Linux orders hard drives alphabetically so your first hard drive would be "sda" your second would be "sdb" your third "sdc" and so on.
And thats all there is to it.

How To: Gather information about your pc using the Linux command line.
Today I will show you how to use the Linux command line to find out all sorts of stuff about your PC hardware and software. There is also a bash script at the bottom of this post that will run all of these commands and save the information into a folder in your home directory and then create a archive of all the files.
Most of these commands should already be installed on your system however lm-sensors and hddtemp you probably need to install. I'll tell you how to install them when we get to them.
Right then on to the list.
sudo dmidecode
The command dmidecode gives you a lot of information about your PCs hardware which is read from the PC's BIOS. While not 100% reliable it's a good way to find out the more obscure stuff about your PC hardware. More information on dmidecode can be found here: http://www.nongnu.org/dmidecode/
sudo lspci
The lspci command lists all the PCI buses and devices connected to your PC, This can include USB controllers, The IDE controller, The SATA controller, As well as all the PCI/PCIe cards you have installed.
sudo lsusb
Similar to the lspci command the lsusb command lists all USB devices connected to the computer.
uname -a
This command displays the name of the PC, the kernel version, the date and time and architecture of your PC.
sudo lsmod
The command lsmod displays all the kernel modules that are currently loaded on your computer.
sudo fdisk -l /dev/sda
This command displays information about your hard drive like size, partitions and the file systems on the partitions as well as a few other details. Note that you may need to change the sda part depending on what type of hard drives you have as well as how many hard drives you have. Use the next command to find out the names of your hard drives.
df -hT
Similar the previous command this one lists all the filesystems mounted on the computer. This command is a good way to find out what your hard drives are called on Linux.
ifconfig -a
This command displays information about all the network interfaces active on your PC. Handy if you are setting up a network connection.
uptime
The command uptime displays the current time, how long the computer has been running, how many users are logged on and the load average for the past 1, 5 and 15 minutes.
echo $PATH
This command displays the contents of your $PATH variable. This is basically a list that the system uses to find executables when you call a command (like echo for example) so you don't have to go to the directory where the executables are before executing them.
To install the last two commands simply type this into a terminal:
sudo apt-get install lm-sensors hddtemp
And type in your password when prompted. Now you can use the "sensors" command and the "hddtemp" command. before you can use the "sensors" command you need to run:
sudo sensors-detect
This command scans your computer for any sensors it can find. It will ask you whether you want to scan for different types of sensors. Say yes to all these questions. When it's done it will show a list of drivers that are needed for the sensors that it finds. It will ask if you want to add these drivers to your "/etc/modules" file. Say yes here. Now you can run the sensors command:
sudo sensors
The sensors command displays the temperatures of all the temperature sensors as well as the RPM speed of any fan speed sensors.
sudo hddtemp /dev/sda
As the name might suggest this command displays the temperature of all the hard drives connected to your computer. As with the fdisk -l command you may need to change the sda part depending on what type of hard drives you have as well as how many hard drives you have. Use the df -hT command to find the names of your hard drives.
Finally here is that bash script that will run all of these commands and put the output of each of the commands into a file and put all of those files into a directory called PCinfo in your home folder. It will also create a .tar archive in the directory that the script is with all the files in.
I've also added a few commands that copy the syslog, apport.log and kern.log files as well as the fstab file into the PCinfo folder as well as these can also be useful for finding information about the Linux system.
Again where hard drive names are just simply replace them with your own. I may improve this at some point so if I do I'll try and remember to edit this post to update it as well as post it separately.
To use this bash script simply copy the following code and paste it into a empty text file and save it. Then you just need to allow it to be executed, To do this go to the directory the script file is in in a terminal and type this in:
chmod 755 PCinfo
Hit enter and it should now be able to be executed. What follows is the bash script:
#!/bin/bash
mkdir ~/PCinfo
sudo dmidecode > ~/PCinfo/dmidecode
sudo lspci > ~/PCinfo/pci_devices
sudo lsusb > ~/PCinfo/usb_devices
cp /var/log/syslog ~/PCinfo/
cp /var/log/apport.log ~/PCinfo/
cp /var/log/kern.log ~/PCinfo/
sensors > ~/PCinfo/sensors
uname -a > ~/PCinfo/uname
sudo lsmod > ~/PCinfo/lsmod
sudo fdisk -l /dev/sda > ~/PCinfo/disks
sudo hddtemp /dev/sda > ~/PCinfo/hddtemp
cp /etc/fstab ~/PCinfo/
df -hT > ~/PCinfo/disk_info
ifconfig -a > ~/PCinfo/network_info
uptime > ~/PCinfo/uptime
echo $PATH > ~/PCinfo/PATH
tar -cvf PCinfo.tar ~/PCinfo
Most of these commands should already be installed on your system however lm-sensors and hddtemp you probably need to install. I'll tell you how to install them when we get to them.

A few useful websites for starting out using Linux.
Hello all. I thought i would put together a few useful links to help people start out with Linux.. The first place you should go if you are new to linux is the Wikipedia page here:
http://en.wikipedia.org/wiki/Linux
It has loads of information on Linux. The next website is DistroWatch.com which is a very handy website for finding linux distributions. Its also a great place for keeping up with updates for different distro's. Here's the link:
http://distrowatch.com/
Next is www.kernel.org which is the place to go to get the latest version of the Linux kernel. You can also download a few Linux distro's from there. The link:
http://www.kernel.org/
another useful website is The Linux Documentation Project. It has loads of HOWTOs that can be a lot of help. The link:
http://www.tldp.org/docs.html#howto
Next up is the forums. Forums are one of the biggest places to find and ask for help. here's a few that i use and find very useful:
http://www.linuxforums.org/
http://www.linuxquestions.org/
http://ubuntuforums.org/index.php
And that all i can think of for now. hopefully you will find these websites useful and that you will choose to try Linux as it is a very good operating system and absolutely free. till next time.
