A few weeks ago I posted in the forums Tocco, which is a Python utility that is able to grab a good amount of OSX system info. In hopes of speeding things up, I began researching OSX commands that give partial system info and wrote a few bash scripts that some folks in here might find useful.
Do note that the multiline commands can be simply put into one line -- my intention wasn't to make things look obscure. I do not believe there is a feasible way to grab the following out-of-the-box from OSX (but would love to be proven wrong):
- CPU Temperature
Battery Temperature
Note: All of these commands are native to OSX. None of these commands require sudo. Contributions to this thread are welcomed. 
Battery
Percent Left
pmset -g batt | grep "InternalBattery" | awk '{print $3+0"%"}'
Time Left
pmset -g batt | grep "InternalBattery" | awk '{print $5}'
Temperature
Fahrenheit
bc <<< "scale=2; ((($(ioreg -r -n AppleSmartBattery | grep Temperature | awk '{print $3}')/10.0)-273.30) * 9/5) + 32"
Celsius
bc <<< "scale=2; (($(ioreg -r -n AppleSmartBattery | grep Temperature | awk '{print $3}')/10.0)-273.15)"
CPU
Percentage Being Used
/usr/bin/top -ocpu -R -F -l 1 | grep "CPU usage" | awk '{print $3+$5"%"}'
Disk
Percentage Free
df | grep disk1s1 | awk '{print 100-$5"%"}'
Free Disk
df -h | grep disk1s1 | awk '{print $4"B"}'
Used Disk
df -h | grep disk1s1 | awk '{print $2"B"}'
Memory
Replace free in the grep -w "free" statement to pull a different values. Available values:
freeinactiveactivespeculative- Others in
vm_statcommand.

bth $(vm_stat | grep -w "free" | awk '{print $3*4096}')
Bluetooth
Is Device Connected
Change the device_name to whatever Bluetooth device you have on your computer. Prints either "Yes" or "No."
export device_name="AirPods"
echo $(system_profiler SPBluetoothDataType 2> /dev/null | grep $(echo $device_name) -A 7 | grep Connected) | awk '{if($1==""){print "No"}else{print $2}}'
Network
