Test
You can now test the module with:
sudo YLightSensor any get_currentValue
Ok, so lets package that up into a bash script:
sudo touch /usr/bin/light_level sudo chmod 777 /usr/bin/light_level sudo vim /usr/bin/light_level
#!/bin/bash # Execute the command and capture the output output=$(sudo YLightSensor any get_currentValue) # Extract the whole number using awk whole_number=$(awk -F' ' '{print int($NF)}' <<< "$output") # Print the whole number echo "$whole_number"
