如何打印bash数组中的所有元素?

我正在bash中运行此脚本,以将用户列表添加到数组,然后将其写入文件。这是脚本:

echo "Insert the first user of the list"
read -r user_name
user_list=()
echo "User $user_name inserted!"
user_list+=($user_name)

echo "Do you want to insert another user?(yes or no)"
read -r answ
while [ $answ == "yes" ]; do
     echo "Enter a new user to insert"
     read -r new_user
     user_list+=($new_user)
     echo "Users list contains:"
     echo "$user_list"
     echo "Do you want to add another user?(yes or no)"
     read -r answ
done

echo "$user_list" > user_list.txt;

除了数组只包含第一个元素外,其他所有东西都工作正常。我不明白为什么不将$ new_user添加到数组中。

最后一行可能是

printf "%s\n" "${user_list[@]}" >user_list.txt
