Using python

import subprocess
cli_cmd = "lscpu"
output = subprocess.check_output(cli_cmd.split()).decode()
unzipped = [ [y.strip() for y in x.split(":")] for x in output.split('\n') if x]
keys = [x[0] for x in unzipped if x]
values = [x[1] for x in unzipped if x]
data = dict(zip(keys, values))
print(data)

Memory Information

Overview (quick)

Command

free

use free -h for human readable response

Example Results

              total        used        free      shared  buff/cache   available
Mem:        8208420      136356     7842076       16796      229988     7840268
Swap:             0           0           0

Overview (Detail)

cat /proc/meminfo

To narrow results use grep such as:

Command

grep MemTotal /proc/meminfo

Example Results

MemTotal:        8208420 kB

or

Command

grep MemFree /proc/meminfo

Example Results

MemFree:         7842052 kB

Using python

import subprocess
cli_cmd = "cat /proc/meminfo"
output = subprocess.check_output(cli_cmd.split()).decode()
unzipped = [ [y.strip() for y in x.split(":")] for x in output.split('\n') if x]
keys = [x[0] for x in unzipped if x]
values = [x[1] for x in unzipped if x]
data = dict(zip(keys, values))
print(data)

Tempature

CPU Temp

Command

CPU_TEMP=$(</sys/class/thermal/thermal_zone0/temp)
echo "$((CPU_TEMP/1000)) c"

You can also use vcgencmd measure_temp Example Results

temp=46.0'C

Using Python

import subprocess
cli_cmd = "cat /sys/class/thermal/thermal_zone0/temp"
cpu_temp = subprocess.check_output(cli_cmd.split()).decode()
cpu_temp = int(cpu_temp) / 1000
print(cpu_temp, 'c')

GPU Temp

Command

/opt/vc/bin/vcgencmd measure_temp

You can also use vcgencmd measure_temp Example Results

temp=46.0'C

Using Python

import subprocess
import re
cli_cmd = "/opt/vc/bin/vcgencmd measure_temp"
gpu_temp = subprocess.check_output(cli_cmd.split()).decode()
matches = re.findall(r"(?P<temp>\d+\.\d+)", gpu_temp)
print(matches[0], 'c')
