Finding MacBook power status from command line (AC plugged in, or not)? I want to start some rsync jobs in macOS Sierra 10.12 when the power and home network are connected, I know how to use the ipconfig command to check the IP address, but is there anyway to tell whether the power is connected besides grepping the system_profiler? (Which seems a lengthy exercise to get the small snippet)
The pmset command has much shorter output than system_profiler:

pmset -g batt


The first line on my MacBook says "Now drawing from ..." either "AC Power"  or "Battery Power" when it runs.
