was said earlier: 1) That "set +e ... set -e" seems -really- bogus. That forces exit on non-zero exit status from simple commands, and this script intentionally invokes some simple commands that might exit non-zero, such as the expr line on the very next line after the "set +e". $ help set "-e Exit immediately if a command exits with a non-zero status." "Using + rather than - causes these flags to be turned off." So as I understand: "set +e" make sure that it will NOT exit script because of the non-zero expr results. Which seems ok.
