Measure Raspberry Pi CPU / GPU / Core / SD clock speeds and check whether you are undervolted
#!/bin/bash
# This bash script outputs the status of your Pi and checks whether you are being throttled for undervoltage and gives you your temperature
# Author James A Chambers 6-6-17
# Output current configuration
vcgencmd get_config int | egrep "(arm|core|gpu|sdram)_freq|over_volt"
# Measure clock speeds
for src in arm core h264 isp v3d; do echo -e "$src:\t$(vcgencmd measure_clock $src)"; done
# Measure Volts
for id in core sdram_c sdram_i sdram_p ; do echo -e "$id:\t$(vcgencmd measure_volts $id)"; done
# Measure Temperature
vcgencmd measure_temp
# See if we are being throttled
throttled="$(vcgencmd get_throttled)"
echo -e "$throttled"
if [[ $throttled != "throttled=0x0" ]]; then
echo "WARNING: You are being throttled. This is likely because you are undervoltage. Please connect your PI to a better power supply!"
