The most common use case would probably be to see if a directory is empty or not, like: compgen -G 'dir/@(*|.*)' >/dev/null || echo 'dir is empty' I don't see it mentioned in https://mywiki.wooledge.org/BashFAQ/004 but I think it's nice because you don't need subshells and don't have to fiddle with shopt, etc.
