System Information

Just want to share a few useful utilities and commands for monitoring/displaying hardware information.

1. Showing information from sensors in your systems.

sensors

This utility tell you information such as temperature in your system.  To install it, you 

apt-get install lm-sensors

If you don't like command line, you can try psensor which extract information from lm-sensors and shows graphically.

2. Showing information about your CPU.

cat /proc/cpuinfo

This command allows you to find out CPU installed without opening up your computer.  This may not be useful if you built/bought the computer yourself.  However, this is very useful to have if you are fixing a computer from someone or you get freebie.

3. Showing memory information

cat /proc/meminfo
