`curl ifconfig.me` 在 shell 脚本中表现不同

我只是尝试了一个简单的基于菜单的 shell 脚本来获取我系统的公共 ip。使用 ( curl ifconfig.me ) .. 但我发现它的行为有所不同。

在这里我试过：

anupam@JAZZ:~/Desktop$ cat menuui
#
# Script to create simple menus and take action according to that selection
# menu item
#
while :
do
    clear
    echo "___________________________________"
    echo "Main Menu"
    echo "___________________________________"
    echo "[1] Show Today's date/time"
    echo "[2] Show files in current directory"
    echo "[3] Show calendar"
    echo "[4] Start a calculator"
    echo "[5] Start editor to write letters"
    echo "[6] Show your public ip"
    echo "[7] Exit/Stop"
    echo "===================================="
    echo -n "Enter your menu choice[1-5]:"
    read yourch
    case $yourch in
    1) echo "Today is `date` ,press a key..." ; read ;;
    2) echo "Files in `pwd` "; ls -l;echo "Press a key..."; read;;
    3) cal; echo "Press a key..." ; read ;;
    4) bc;;
        5) vi;;
        6) echo "Your public ip is `curl ifconfig.me`";;
    7) exit 0 ;;
    *) echo "Opps!!! Please select choices 1,2,3,4 or 5";
    echo "Press a key...";read;;
    esac
done

然后我执行了它...

这不是我期望的..我怎么能解决这个问题？
