A little sysinfo script for CLI - Raspberry Pi Development

EDIT: I've updated the script with a bit more info.
All you need is the additional package "bc".
Code:
#!/bin/bash
cpuUsageM=$(top -bn 1 | awk '{print $9}' | tail -n +8 | awk '{s+=$1} END {print s}')
cpuFreqM=$(echo "scale=0; " `cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq` "/1000" | bc)
cpuTempM=$(echo "scale=1; " `cat /sys/class/thermal/thermal_zone0/temp` "/1000" | bc)
gpuTempM=$(/opt/vc/bin/vcgencmd measure_temp)
gpuTempM=${gpuTempM//\'C/}
gpuTempM=${gpuTempM//temp\=/}
memTotalM=$(cat /proc/meminfo | grep MemTotal | awk '{print $2}')
memTotal1=$memTotalM
memTotalM=$(echo "scale=1; $memTotal1 / 1024" | bc)
memUsageM=$(cat /proc/meminfo | grep MemFree | awk '{print $2}')
memUsageM=$(echo "scale=1; ($memTotal1 - $memUsageM) / 1024" | bc | sed 's/^\./0./')
memUsageP=$(echo "scale=1; (100/$memTotalM) * $memUsageM" | bc | sed 's/^\./0./')
rootTotalM=$(df -m / | grep / | awk '{print $2}')
rootTotalM=$(echo "scale=1; $rootTotalM / 1024" | bc)
rootUsageM=$(df -m / | grep / | awk '{print $3}')
rootUsageM=$(echo "scale=1; $rootUsageM / 1024" | bc | sed 's/^\./0./')
rootUsageP=$(echo "scale=1; (100/$rootTotalM) * $rootUsageM" | bc | sed 's/^\./0./')
echo "CPU Usage: $cpuUsageM%"
echo "CPU Freq: "$cpuFreqM"MHz"
echo "CPU Temp: $cpuTempM°C"
echo ""
echo "GPU Temp: $gpuTempM°C"
echo ""
echo "MEM Usage: "$memUsageM"MB/"$memTotalM"MB ($memUsageP%)"
echo "Root Usage: "$rootUsageM"GB/"$rootTotalM"GB ($rootUsageP%)"
The output is as follows:
Code:
~$ ./sysinfo
CPU Usage: 70.1%
CPU Freq: 800MHz
CPU Temp: 57.8°C
GPU Temp: 58.4°C
MEM Usage: 96.5MB/375.4MB (19.3%)
Root Usage: 0.9GB/7.2GB (12.4%)

That is actually insanely useful. Wish I saw this a little earlier, it would of saved a lot of time.

Thanks. This script just what I was looking for

---

Cheers i will try and get this to output via php for a little site i'm making for my pi.

thx for sharing

Perfect
