How to get pin level?

[bfallc]

hi,

In terminal:
raspi-gpio get 4

returns:
GPIO 4: level=0 fsel=0 func=INPUT pull=UP

How can I just get the level, the state of the pin, the "0" or "1" out of this? For example, how can I use this in an if statement to determine pin state?

I'm in bash but any examples of using raspi-gpio in logic would be really awesome, I'm struggling.

Thanks.

Do a string match for level=1 (or level=0).
