Create a Simple Script to Get System Information - cogitech - 12-21-2023

I found this elsewhere and then modified it a bit to add more info.

Simply ssh into your moode and then

nano your_file_name.sh

and then paste this in it and save the changes:

Code:
#!/bin/bash

# Script: my-pi-temp.sh

# Purpose: Display the ARM CPU and GPU  temperature of Raspberry Pi 2/3 

# Author: Vivek Gite <www.cyberciti.biz> under GPL v2.x+

# Edits by: Cogitech (add Core Volts and CPU Freq)

# -------------------------------------------------------

cpu=$(</sys/class/thermal/thermal_zone0/temp)

echo "$(date) @ $(hostname)"

echo "-------------------------------------------"

echo "GPU temp   => $(vcgencmd measure_temp)"

echo "CPU temp   => $((cpu/1000))'C"

echo "Core Volts => $(vcgencmd measure_volts)"

echo "CPU Freq   => $(sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq) KHz"

Then do:

Code:
chmod +x your_file_name.sh

To run the script, simply:

Code:
./your_file_name.sh

The output will look something like:

Code:
Wed Dec 20 17:18:46 MST 2023 @ moode

-------------------------------------------

GPU temp   => temp=45.7'C

CPU temp   => 46'C

Core Volts => volt=0.8600V

CPU Freq   => 700000 KHz

You can also do the following if you want to monitor this info while playing music, running tests (resampling, EQ, DSP, etc.)

Code:
watch ./your_file_name.sh

Here is another variation, which displays the CPU speed in MHz, but requires you to use "sudo" when you run it:

Code:
#!/bin/bash

# Script: my-pi-temp.sh

# Purpose: Display the ARM CPU and GPU  temperature of Raspberry Pi 2/3 

# Author: Vivek Gite <www.cyberciti.biz> under GPL v2.x+

# Edits by: Cogitech (add Core Volts and CPU Freq)

# -------------------------------------------------------

cpu=$(</sys/class/thermal/thermal_zone0/temp)

freq=$(</sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq)

echo "$(date) @ $(hostname)"

echo "-------------------------------------------"

echo "GPU temp   => $(vcgencmd measure_temp)"

echo "CPU temp   => $((cpu/1000))'C"

echo "Core Volts => $(vcgencmd measure_volts)"

echo "CPU Freq   => $((freq/1000)) MHz"

Displays this:

Code:
moode@moode:~ $ sudo ./my-pi-temp.sh 

Wed Dec 20 17:36:49 MST 2023 @ moode

-------------------------------------------

GPU temp   => temp=45.7'C

CPU temp   => 45'C

Core Volts => volt=0.8600V

CPU Freq   => 1500 MHz
