因此，我有一个对话框菜单（代码如下），它工作得很好。但我发现，#1 一旦选择了某个项目，它就会离开对话框，#2 一旦选择了某个项目，它就不会再回到对话框。
那么，我如何确保一切都保持处于状态dialog，然后返回到dialog除非退出？
这是我目前拥有的代码：
#!/bin/bash
cmd=(dialog --clear --backtitle "Get You Online Commander" --title "Get You Online Commander" --menu "What would you like to do?" 20 40 11)
options=(0 "Install/Update the Commander"
1 "Create a New Site"
2 "Install a Wordpress Site"
3 "Account Backup"
4 "Account Restore"
5 "Terminate an Account"
6 "Generate SSL Certificates"
7 "Optimize Images"
8 "Restart Commander Services"
9 "Clear Server Cache"
10 "Prime Websites Caches")
while true; do
choices=$("${cmd[@]}" "${options[@]}" 2>&1 >/dev/tty)
# If cancelled, drop the dialog
if [ $? -ne 0 ]; then
clear;
exit;
