Linux里面可以在命令行里形成对话框，用光标上下，左右选择，一屏一屏的问答选择，填写。whiptail是Linux不需要另行安装，默认就有的，其它的比如dialog需要另行安装，很麻烦，虽然功能比较好些。
帖一个写好的东西。#!/bin/bashtrap “” 2while truedoOPTION=$(whiptail –title “Email Manager” –nocancel –menu “Choose your option” 15 60 4 \”1″ “Add Email User” \”2″ “Delete Email User” \”3″ “List Email User” \”4″ “EXIT” 3>&1 1>&2 2>&3) case $OPTION in 1) EmailAddress=$(whiptail –title “EmailAddress-form Input Box” –inputbox “What is your add EmailAddress?” 10 60 @shenxu.com 3>&1 1>&2 2>&3) exitstatus=$? if [ $exitstatus = 0 ]; then grep $EmailAddress /etc/postfix/virtual_mailbox_maps>/dev/nul exitstatus=$? if [ $exitstatus = 0 ]; then whiptail –msgbox “The Email Address is a existed” 10 40 elif (whiptail –title “Add Yes/No Box” –yesno “Are you sure add $EmailAddress.” 10 60) then /etc/postfix/mailadd.sh $EmailAddress whiptail –msgbox “The Email Address $EmailAddress is a added.” 10 40 fi else whiptail –msgbox “You chose Cancel.” 10 40 fi ;; 2) EmailAddress=$(whiptail –title “EmailAddress-form Input Box” –inputbox “What is your Delete EmailAddress?” 10 60 @shenxu.com 3>&1 1>&2 2>&3) exitstatus=$? if [ $exitstatus = 0 ]; then grep $EmailAddress /etc/postfix/virtual_mailbox_maps>/dev/nul exitstatus=$? if [ $exitstatus != 0 ]; then whiptail –msgbox “The Email Address $EmailAddress is a not exist.” 10 40 elif (whiptail –title “Add Yes/No Box” –yesno “Are you sure delete $EmailAddress.” 10 60) then /etc/postfix/maildel.sh $EmailAddress whiptail –msgbox “The Email Address $EmailAddress is a deleted.” 10 40 fi else whiptail –msgbox “You chose Cancel.” 10 40 fi ;; 3) EmailAddress=$(cat /etc/postfix/virtual_mailbox_maps | awk ‘{print $1}’) whiptail –msgbox “The Email User list are $EmailAddress.” –scrolltext 20 40 ;; 4) echo “EXIT” break ;; esacdonetrap : 2
whiptail –title “Email Manager” –nocancel –menu “Choose your option” 15 60 4 \”1″ “Add Email User” \”2″ “Delete Email User” \”3″ “List Email User” \”4″ “EXIT” 3>&1 1>&2 2>&3–title “Email Manager” 是标题，双引号里是自己填的提示信息–nocancel 是在这个图文里面不显示取消，只显示OK–menu “Choose your option” 15 60 4 是表示菜单提示，双引号里是自己填的提示信息，15是高度，60是长度，4是有个选择项目下面的1-4是自己的提示最后比较关键，3>&1 1>&2 2>&3是为了把选择的内容填进变量OPTION
whiptail –title “EmailAddress-form Input Box” –inputbox “What is your add EmailAddress?” 10 60 @shenxu.com 3>&1 1>&2 2>&3–inputbox “What is your add EmailAddress?” 是可以形成一个让用户输入的提示框@shenxu.com 是默认输入text里的值
whiptail –msgbox “You chose Cancel.” 10 40 是显示一行你的提示其实还有–infobox，似乎和msgbox很像，其实不同，它基本上用不上，是在shell运行完后，可以往前翻页能看见的东西–scrolltext 20 40是为了显示多行的时候可以上下滚动
另外还有–passwordbox和text一样输入，就是以***显示whiptail –checklist “choose” 15 60 2 “1” “aa” ON “2” “bb” ON15 60还是高和宽，2是有几个选项，和menu一样，后面多了一个ON或者OFF表示状态，就是菜单出来后默认是不是选，，On是选，OFF不选，用空格键来选择。可以多选。–radiolist，不可以多选了。ON就只能有一个，其它必须是OFF还有一个显示进度条的–gauge，我觉得没啥用处。#!/bin/bash{ for n in `seq 100` do sleep 1 echo $n done} | whiptail –gauge “Please wait while installing” 6 60 0
