Running dss.sh on linux will emit a "too many arguments" or "unexpected operator" error.

The issue is with line 52 of the dss.sh script:

if [ $OTHERARGS = "" ]; then

$OTHERARGS should be wrapped in quotes:

if [ "$OTHERARGS" = "" ]; then

Or perhaps using the -z option below is better:

if [ -z $OTHERARGS ]; then
