Linux命令——whiptail交互式shell脚本对话框

转自:交互式shell脚本对话框----whiptail指令

当你在linux环境下setup软件的时候就会有相应的对话框让你输入。虽然我们已经习惯了这种交互的方法,但是如果有一种直观的界面来输入是不是会更加友好和方便呢,在shell脚本中你可以使用-whiptail指令来完成。

消息框

语法:

1
whiptail --title "<message box title>" --msgbox "<text to show>" <height> <width>

实例:

1
whiptail --title "Message box title" --msgbox " Choose Ok to continue." 10 60

 yes/no对话框

    echo "You chose Yes. Exit status was $?."
else
    echo "You chose No. Exit status was $?."
fi
