cleanupmenu
With that exec statement you set the script's standard-in to a file. Then with that loop you read all the data. At this point, standard-in is at end-of-file. Then you call cleanupmenu which contains a read statement. That read statement will try to read one more line from the $QL_LOG2 file but it won't succeed. You need to add
exec < /dev/tty
before you invoke cleanupmenu to put standard-in back to being the tty.
