What's the difference between $@ and $* in UNIX?

Question

What\'s the difference between $@ and $* in UNIX? When echoed in a script, they both seem to produce the same output.

Answer 1

It's safer to use "$@" instead of $*. When you use multiword strings as arguments to a shell script, it's only "$@" that interprets each quoted argument as a separate argument.

As the output above suggests, if you use $*, the shell makes a wrong count of the arguments.
