Full Discussion: Difference between $* and $@

You can find the difference between $* and $@ only when you use them within quotes

$* will combine all arguments to a single string
$@ will have each arguments as a seperate string

See the below example

Code:
/export/home/test/mons>cat samp.sh
for i in "$*"
do
print $i
done
for i in "$@"
do
print $i
done

/export/home/test/mons>samp.sh hai welcome to "Unix Forum"
