How to get Hard disk,CPU infomation and temperature in Ubuntu

How to get Hard disk,CPU infomation and temperature in Ubuntu: "First,open up terminal from Applications/Accessories/Terminal,and run:

sudo hdparm /dev/sdc

Output:

/dev/sdc:
multcount = 16 (on)
IO_support = 0 (default)
readonly = 0 (off)
readahead = 256 (on)
geometry = 19457/255/63, sectors = 312581808, start = 0

CPU info.

cat /proc/cpuinfo

Output example:

processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 95
model name : AMD Athlon(tm) 64 Processor 3000+
stepping : 2
cpu MHz : 1799.564

CPU Temperature

Option 1:

cat /proc/acpi/thermal_zone/THRM/temperature

This requires kernel modules support,and enable this in kernel option.

Option 2:

Install lm-sensors:

sudo apt-get install lm-sensors

Then run:

sensors-detect

there will be some questions and you can answer them all YES.
Now,use this command and you will get cpu temperature:

sensors

k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +44.0°C
Core1 Temp: +34.0°C
