Who <associated> +%Y with "2016" ? The command "date" did. This says to run the date command with the argument being the output of the echo command. In this case the latter as +%Y so this is running date +%Y which is the year in which the date command was run. The ouput is then the argument to the outter echo command. > Lets have some examples of nesting, without extra spooky-stuf. extra spooky-stuf? man date > >
