Setting GPIO value on boot

Question

I'm a semi-linux newcomer and i have a question:

I need to set some GPIO pins in this way: (pin 18 out, pin 17 in) (actually i'm doing this via WiringPi(pyton) trought this commands)

gpio export 18 out

gpio export 17 in

All Works fine if i run these commands via terminal. However i have set these commands in

/etc/rc.local

before exit 0

to run it at boot, but after some tryies it won't work. It could be a path problem? Any help is appreciated, Thanks mboy.

Path thing - yes, better fix it to using full path. What happens when you run /etc/rc.local - are you getting any output, is the script runnable?
Ok, but i'dont know how to set full path.. it's the first time that i use rc.local and wiringpi..

I've fixed it! All i needed is to set full path. In my case /usr/local/bin/gpio export 18 out because gpio is a third party command. Thanks!
