如何结束一个shell脚本？

Question

我正在 Linux 上编写一个脚本，我想添加一点额外的内容并询问用户是否要退出该程序，任何人都可以帮助我弄清楚如何做到这一点吗？

尝试这个：

read -p "Do you want to continue? (y/N) " ANS
    # if not, do something else, otherwise fall out the bottom
    [ "$ANS" = "y" -o "$ANS" = "Y" ] && {
            # commands here what to do if we stick around
            echo "OK, we will continue"
            # better put something else to do here or we'll fall out anyway.
            }
