You were pretty close. First, you got right using $@ instead of $*.

You need to worry about shell expansion so don't use " unnecessarily as happened in the assignment. That will remove the boundaries between tokens. However you do need it around "@_".

So we have:

if [ $# -eq 0 ]; then
   echo "Usage is $0 <files to be tested>"
   exit
fi

for filetobetested in "$@"
do
    file "$filetobetested"
done

Lastly, my bash debugger http://bashdb.sf.net can help you follow stuff like this.
