Exit code not correct

[jsseidel]

There are points in mktechdocs where the exit code doesn't work as expected.

After while loops, instead of this:

[[ $? != 0 ]] && exit $?

You need this to preserve the exit code. At the point of the exit, you'll get the exit code of the [[ ]] statement (0) instead of the the exit from the while loop.

RV=$? ; [[ $RV != 0 ]] && exit $RV

Fixed and pushed.
