Given string to exec is invalid.
http://gambasdoc.org/help/lang/exec?v3


shell "sudo sh -c 'echo out /sys/class/gpio/gpio27/direction'"

Why this would do anything?
sudo is without any input, unnecessary "sh -c" and then command which
output should be "out /sys/class/gpio/gpio27/direction". If you want to put
word "out" to file, you need to use direction. Example "echo out >
/sys/class/gpio/gpio27/direction". I don't think your command works in
terminal either.

Maybe you want to do something like this: "gksudo echo out >
/sys/class/gpio/gpio27/direction" ?
