Environment variables on Linux - linux

Question

I am hoping that you're able to help me I am trying to understand how use the /proc file system or profile settings. I am trying to write a script which pulls the temp of the CPU and a list of peripherals attached to a SUSE device. This would be using native functionality rather than a tool. Is there a path of sorts to the variable for temp of the CPU and a list of attached devices?
Hopefully it makes sense.

Answer 1

To get temp use "sensors":
$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +63.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +60.0°C (high = +105.0°C, crit = +105.0°C)
or look at the /sys/class/hwmon/
$ cd /sys/class/hwmon/hwmon0/device/
{ cat temp3_label; cat temp3_input; }
Core 1
58000
