Tip #537   Run a command when not busy

You can use the following to run a command only when the load average is below a certain level 

echo "cp /large_folder /backup/" | batch

This is great for one off jobs that you want to run at a quiet time. The default threshold is a load average of 0.8 but this can be set using atrun.
