为什么此脚本的输出中没有出现波浪号扩展？

#!/bin/bash

read -p "Enter filename: " fname
if [[ -d $fname ]]
then
        echo "$fname is a directory"
else
        echo "$fname is not a directory"
fi

输出：

$ bash -x test_cd.sh 
+ read -p 'Enter filename: ' fname
Enter filename: ~/Music
+ [[ -d ~/Music ]]
+ echo ' ~/Music is not a directory'
 ~/Music is not a directory
