Linux里面能夠在命令行里造成對(duì)話框，用光標(biāo)上下，左右選擇，一屏一屏的問答選擇，填寫。shell

whiptail是Linux不須要另行安裝，默認(rèn)就有的，其它的好比dialog須要另行安裝，很麻煩，雖然功能比較好些。bash

帖一個(gè)寫好的東西。ide

#!/bin/bash

trap "" 2

while true

do

OPTION=$(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

echo "EXIT"

break

trap : 2post

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命令行

--title "Email Manager" 是標(biāo)題，雙引號(hào)里是本身填的提示信息orm

--nocancel 是在這個(gè)圖文里面不顯示取消，只顯示OKip

--menu "Choose your option" 15 60 4 是表示菜單提示，雙引號(hào)里是本身填的提示信息，15是高度，60是長度，4是有個(gè)選擇項(xiàng)目input

下面的1-4是本身的提示it

最后比較關(guān)鍵，3>&1 1>&2 2>&3是為了把選擇的內(nèi)容填進(jìn)變量OPTIONio

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?" 是能夠造成一個(gè)讓用戶輸入的提示框

@shenxu.com 是默認(rèn)輸入text里的值

whiptail --msgbox "You chose Cancel." 10 40 是顯示一行你的提示

其實(shí)還有--infobox，彷佛和msgbox很像，其實(shí)不一樣，它基本上用不上，是在shell運(yùn)行完后，能夠往前翻頁能看見的東西

--scrolltext 20 40是為了顯示多行的時(shí)候能夠上下滾動(dòng)

另外還有--passwordbox和text同樣輸入，就是以***顯示

whiptail --checklist "choose" 15 60 2 "1" "aa" ON "2" "bb" ON

15 60仍是高和寬，2是有幾個(gè)選項(xiàng)，和menu同樣，后面多了一個(gè)ON或者OFF表示狀態(tài)，就是菜單出來后默認(rèn)是否是選，On是選，OFF不選，用空格鍵來選擇。能夠多選。

--radiolist，不能夠多選了。ON就只能有一個(gè)，其它必須是OFF

還有一個(gè)顯示進(jìn)度條的--gauge，我以為沒啥用處。

#!/bin/bash

{

for n in `seq 100`

do

sleep 1

echo $n

done

} | whiptail --gauge "Please wait while installing" 6 60 0
