difference between $@ and $* in bash script [duplicate]

Answer 1

If you have a script foo.sh:

asterisk "$*"
at-sign "$@"

and call it with:

./foo.sh "a a" "b b" "c c"

it's equivalent to:

asterisk "a a b b c c"
at-sign "a a" "b b" "c c"

---

Without the quotes, they're the same:

asterisk $*
at-sign $@

would be equivalent to:

asterisk "a" "a" "b" "b" "c" "c"
at-sign "a" "a" "b" "b" "c" "c"
