oh, come on, i am merely conveying what i got in the mail!
anyway, i tried...
i=0
while [ $i -le 32767 ]
do
echo -n $i' '
if [ $RANDOM = $RANDOM ]
then
echo same
else
echo diff
fi
i=$(( $i + 1 ))
done
...the above more than three times each in bash-2.05 &
ksh93-20020317 (i.e. more than 3 * 2 * 2^16 times) and did not get
any utterance of 'same'. not that that proves anything...
