Run this script in the background. A log file will be created at /b1n.log. Because we need to do this line by line, echo and log instructions should be left out since those are only for debugging. Define the functions too, but make it on one line like this: NAME() { BLAH }. Remember to leave out all log instructions and leave out >$LOG 2>&1.
