What does putting quotes around $@ in bash script do? i.e. "$@" instead of $@

Question

I was getting errors passing in a command and when I put quotes around that things worked just fine. Just curious how that works.

Answer 1

Double quotes around $@ (and similarly, ${array[@]}) prevents globbing and word splitting of individual elements, while still expanding to multiple separate arguments.
