I am trying to enable ethernet iot card however when entering  
echo 2 \> /sys/class/gpio/export of the three echo commands (see below) to take the card out of reset and enable ethernet I get this error that my permission is denied. I even tried giving myself permission using the chmod command (see image). Nothing is working and it is quite frustrating. Can anybody help.

Echo commands to enable ethernet:  
echo 2 \> /sys/class/gpio/export  
echo out \> /sys/class/gpio/gpio2/direction  
echo 1 \> /sys/class/gpio/gpio2/value
