I think fuzyok doesn't like you. :-)
There's a difference between $*, $@ and "$@". You need to read the bash
man page about 50 times. It's all there.
If you do globbing on the commandline (like you should) then you have a
couple of ways to write your script.
One way is to process all of the arguments in the commandline like you did
above
for ii in "$@"
Another way is to have a loop that always refers to $1 and to call shift
after processing an argument
while [[ -n "$1" ]]
do
dosomething $1
shift
done
And, you can get $1 to be * (if you really really want to). I suspect you
don't. Just run your program with the * in single quotes to prevent
expansion.
