If it took you FOUR HOURS to do this, you're in trouble. Also, you say you're working for a 'small company', but I cannot think of ANY reason why a 'company' would need a shell script to do what you're asking for. This is homework, so please be honest about it.
If you bothered to look at the bash scripting tutorial I posted to you before (or if you showed ANY effort into looking things up before you came here), you'd have had your solution. Again, we will spoon-feed you an answer: http://tldp.org/LDP/abs/html/interna...s.html#ARGLIST
It shows you how to read multiple command-line arguments, and print them out. And 'rev' was mentioned...look it up.
x=$@ # copy parameters to variable x
result=$(echo $x | rev | cut -d ' ' -f 2-)
echo $result ${x##*' '}
# echo $x : send x to standard output
# rev : reverse line
# cut -d ' ' -f 2- : delimiter is space -f 2- is print from field 2 to end
# print $result is reversed line except first field
# ${x##*' '} remove all fields from $x except last and print it.
